In Situ Chemistry - In Situ Synthesis of Compounds

In Situ Chemistry - In Situ Synthesis of CompoundsIn situ chemistry is a synthetic method for chemical production, a sort of a laboratory-like environment in which chemicals are produced from a sample already obtained. The name 'in situ' means 'nowhere'.In situ chemistry is used to produce synthetic organic compounds from the compounds already present in nature. Most of the chemical processes that are applied to the production of compounds have been known since ancient times, but the bulk of modern synthetic techniques can be traced back to in situ chemistry, which was first studied by Nobel Laureate Otto Hahn.In situ chemistry is based on the principle of spontaneous generation, as stated by the original source of this terminology. It's the same concept as that of geothermal heat. Chemists call in situ processes 'synthetic' because, in nature, the compounds that are formed under these conditions would not have existed without those conditions.In situ processes include synthesis of t he dyes, antifreeze and other complex compounds by means of manganese metal complexes (oxides of manganese), often by means of catalytic reduction. Synthesis of the degradable polymers of waxes and oils (polyethylene glycol) is sometimes carried out by reacting a polymer, i.e. a polymer with ethers or alcohols. Moreover, in situ production of sodium hydroxide may take place by adding salt to water under high pressure.The whole in situ apparatus for the synthesis of compounds consists of a vessel, a filter bag, the catalyst, and equipment for purifying the sample. Sometimes, in situ processes involve only one step, whereas in case of many reactions, the next step is the synthesis of the next compound.In situ production of molecules can result in the formation of specific useful compounds, known as functional groups. They have properties that are different from those of their molecules. Amongst these compounds are fluorine and nitrogen compounds, the Quaternary ammonium compound, acet ylene, nitrous oxide, nitrogen mustard, carbonyl compounds, amino acids, nitrogen phosphates, hydroxyl radicals, organosilanes, enamyls, hydrogen peroxide, anilines, cations, metals, aromatic and alkaline earth metals, and some alloys and sulphur-containing compounds. The existence of these useful compounds is a scientific fact.It has been estimated that the amount of in situ activity in a typical laboratory is equal to that in an average city of a hundred thousand inhabitants. Most companies deal with in situ processes for the production of chemicals by means of in situ synthesis. In situ chemistry is used in many fields of science. It has to be understood that there are still many unsolved problems to be solved.

Should all exams be taken and submitted using computers - Tutor Hunt Blog

Should all exams be taken and submitted using computers Should all exams be taken and submitted using computers? Should all exams be taken and submitted using computers?Secondary SchoolsA friend of mine is a university examiner - she works for OCR (Oxford, Cambridge and RSA Exams). My understanding was that her job entailed compiling the papers: writing the questions, and making sure that the tests were comprehensively balanced. It turns out though that she has a far more onerous task: she has to mark the exams. `How hard can that be?` I thought to myself? She`ll obviously know what the answers are, she just has to read through each paper and grade it accordingly. I recall asking her if the most difficult part of her job was deciding just how many marks to award a student in a comprehension question, where there isn`t a clearly delineated right and wrong answer. `No, she answered, `The most difficult thing is trying to read students` awful handwriting!` It turns out this is the most common complaint from examiners - they have to decipher hundreds of pages of handwriting, with each student having their own idiosyncratic style of writing. My friend went on to tell me some of her concerns: `Some students have the most beautiful handwriting - while others have such a poor script it makes my eyes hurt! However bad their writing is, I`m obliged to decode it all. It`s not their penmanship that`s being tested - though sometimes the writing is so bad, almost completely illegible, I want to cross it all out and give them no marks at all!` `As the student nears the end of the exam, and time is running out, their writing becomes even worse, as they write faster and faster! I have to make sure i`ve read every line, however enigma-like it may be to decode, as it wouldn`t be fair to a student to gloss over words that might contain the correct answer.` Our current students may well be the last generation who sit examinations using paper and pen, for there are calls for all assessments to be undertaken using computers. There is really no reason why students can`t log into a web site that hosts the exam, and type out their answers, while sitting in a traditional examination hall. The examiner won`t even have to tell students to stop writing at the end of the examination, nor collect their papers once the assessment has concluded. There are many benefits to this method: the questions can be uploaded to the website on the day of the exam, negating the need for hundreds of confidential papers to be stored on school grounds days, or even weeks before the test. There won`t be any more cases of exam papers being stolen and distributed to students before the test, something that frequently happens according to my examiner friend; nor that of completed papers being lost prior to marking, something that also sadly occurs. Many people might balk at the idea of equipping students with computers during exams - while mobile phones are banned from the examination room, computers could be used with even greater facility to access the internet, allowing that elusive answer to be acquired. I suspect it wouldn`t be particularly difficult for schools to set up computers that are disabled in some manner, so they can`t access any Wi-Fi signal, so this is a concern that could likely be alleviated. There are some schools which have for some time mandated that students submit their answers on computers during exams, and I am not aware of any issues being raised. One concern that comes to mind however is that of questions that require an answer in the form of a picture or diagram. Certain questions in geometry or geography might rely upon a picture being submitted by the student, or a presented image being altered in some manner. I suspect this is not really a major problem though - computers are used by graphic artists every day, so it should be perfectly possible for the student to draw, for example, certain geometric shapes, or mark the border between two countries using a mouse. Exams submitted via computer could also provide some useful information to exam boards: they could track how long students take over each question, allowing them to assess the difficulty levels more accurately, helping them create new tests in the future. There will also be an environmental benefit in the reduction of paper use. Exams will be able to be graded faster, and more accurately, and my friend will be spared the punishment of having to decipher reams of spidery, hieroglyphic-like writing! 11 months ago0Add a Comment

8 Practical Ways to Learn All the Foreign Language Vocabulary Needed for Conversational Fluency

8 Practical Ways to Learn All the Foreign Language Vocabulary Needed for Conversational Fluency 8 Practical Ways to Learn All the Foreign Language Vocabulary Needed for Conversational Fluency Did you know that 1,000 words can get you a long, long way in a foreign language?It might not seem that easy when youre looking at the raw numbers. The Oxford English Dictionary  includes  more than 170,000 English word entries.The  Hanyu Da Cidian dictionary  includes  370,000 Mandarin Chinese words, and the Explanatory Dictionary of the Living Great Russian Language  includes  200,000 Russian words. Most languages have similar numbers of words circling around.As a language learner, these numbers can seem downright crazy! How are you ever going to memorize that many vocabulary words?Luckily, you dont need to learn anywhere near  that many words to communicate proficiently. In fact, most native speakers know only a small portion of these totals. The  website TestYourVocab.com  put together statistics  that show that the average English-speaking adult knows only 20,000-35,000 words. Whats more, its estimated  that the top 1,000 lexemes (words or word groupings) account for 80% of all English texts!So simply learning 1,000 words can  get you far in your ability to understand texts and communicate with people.  The same is true for nearly all languages.With a little strategy and the right tools, you can learn much faster and easier than you might have imagined. Follow these steps to get started and boost your foreign language vocabulary learning. 8 Practical Ways to Learn All the Foreign Language Vocabulary Needed for Conversational Fluency1. Narrow it downThe first step to learning effectively is to identify what you want to focus on and set goals.If you have a strong interest in a particular subject, start with that. Perhaps you want to to read about soccer, or you want to learn how to cook like a native chef. The most effective learners are motivated to study because they choose vocabulary based on their interests and needs. If you  select words you dont find useful, youre much less likely to succeed in memorizing them and being able to use them in context. Y ou should be as excited as possible about learning new words!If you have a more general goal, like wanting to be able to communicate with people on an upcoming trip or read the news, its a good idea to focus on the words that are most commonly used in your target language.2. Figure out what the most common words areThis is a good tip for anyone, no matter what your particular interests may be. The most common words will be the most common words in any kind of speech or writing. They pop up everywhere!Typically, there are four general  categories of vocabulary words we can talk about in any language: High-frequency words, academic words, technical words and low-frequency words.You can generally ignore academic, technical and low-frequency words, unless you have specific need to learn them. Focus on  high-frequency words  to  quickly improve your ability  to communicate. These are the words people use most in everyday writing and speech, so learning them will take you in the right dir ection so you can start  understanding what you hear and being able to respond appropriately.An online search for the phrase  most common words in X language can help you identify a list of high-frequency words to focus on, like  this one in Spanish or this one in French. After identifying these words, try doing an online search to find articles and videos that use these words in context.3. Seek out opportunities to use new wordsDo you  know what it means to learn a word?Learning any vocabulary involves two separate processes:Being able to recognize a word when you hear or read itBeing able to say or write a wordIts more difficult  to produce a word than it is to recognize it, so  we typically learn to recognize words in writing or speech before were able to produce them ourselves. It takes additional, concentrated practice to learn a word well enough to  think of it and say or write it when we want to.On an average day, you get much more practice hearing and reading words than you do speaking or writing, whether in your native language or a language youre trying to learn, and even if youre super extroverted and talkative.Thats why its important to always seek out more opportunities for productive language practice, such as  writing emails to friends, writing in a personal journal, talking with others in  a conversation club or chatting with people who dont speak your native language.You can also check out guided conversations like polyglot Olly Richards  Conversations course, which is designed to help you set up workable, step-by-step systems for learning the most common phrases and words in your target language.Opportunities for real-life use of words are also important because you need to learn to use words in context and understand their connotations. Simply memorizing a definition wont necessarily  provide you with enough information to use a word  effectively.4. Break out those flashcardsShuffling those  good ol flashcards is  one of the best ways  to le arn foreign language words.Flashcards are efficient, allow for flexibility and make it possible to stagger your learning with a few minutes of studying here and a few minutes there, adding up to big language gains over time.There are two general types of flashcards, and a third if you count the most innovative variety:DIY paper flashcards. Buy a pack of index cards from the store and start writing vocabulary words on them. Its cheap, easy and low-tech, and its sure to be effective.Digital flashcards. If you prefer to go high-tech, there are many  online and computer software programs  for flashcards, such as  Anki, StudyStack  and Quizlet. Most programs allow you to create your own flashcards and access flashcards other people have created, making it possible to find lists of useful words to study without creating the cards yourself.Multimedia flashcards.  Check out the flashcards offered by FluentU, and you might never go back to other formats. Not only do they operate with SRS to ensure maximum learning productivity, but theyre personalized to match up with the vocabulary youve learned from watching FluentU videos. Plus, the flashcards themselves show you video snippets to better engage your memory!No matter which method you use, there are a few keys to making useful flashcards:Write the foreign language vocabulary word on one side of the card and the meaning of the word in your native language on the other.Keep your cards simple. It can be tempting to include on details like how to conjugate an irregular verbs, but  youll  learn best if your cards have very little clutter on them.Include pictures with your definitions, if possible. Some people learn best with words, while others do better with images. Combining both can help you make the most of your study time.After creating your flashcards, its time to start studying! Here are some tips to get the most from your flashcards:Always take a moment to guess the meaning before turning the card over, even if you re unsure of yourself.Change the order of cards. If youre using a computer program, it will likely do this for you.Start by learning the words receptively. Look at the foreign language word and try to identify its meaning in your native language. After youre comfortable doing this, then work on learning the words by starting with the translation side and identifying the foreign language word.Speak aloud as you practice. You learn words better when you speak rather than simply read them.Use spaced repetition. Gradually increase the amount of time between repetitions of a flashcard. Research  shows that learning through spaced repetition is better than learning through massed repetition. Rather than spending 15 solid minutes reviewing your flashcards and not looking at them again for a week, its better to review them in shorter intervals each day or several times a day and to review them again every few days, increasing the amount of time between each repetition. Some  computer flashc ard programs do this for you.Flashcard learning is  an extremely effective method of learning, but it doesnt provide opportunities to learn words in context. Make sure to combine your flashcard learning with opportunities to read, listen, watch and speak.5. Learn new words in contextLearning in context means being exposed to new words through reading or listening.  This enables  you to naturally run across unfamiliar words and learn their meanings.Research shows that people learn words best when they see them used in context, so seek out opportunities to learn new words from sources such as:Books  and  magazine or news articlesOnline videos, TV shows and filmsAudiobooksTextbooks, which usually provide lists of words and texts to help you practice themTalking with a conversation partner or friendThis strategy can be used alone or in combination with other methods such as flashcards or using a dictionary.When learning in context, its important to choose  texts and conversation  opport unities that wont be overwhelming. You need to be able to recognize most of the words you read or hear so that  you can identify the  new words. Researchers suggest that a ratio of one new word to every 20-50 familiar words is ideal.Learning in context is slower than learning with flashcards because you arent as focused on the sole task of memorizing, and because you need to do a lot of reading or listening before you encounter a new word. However, its very effective because it provides you with a lot of information about a new word. It also provides lots of practice using your target language, reviewing other vocabulary words and practicing grammar structures.One great way to learn in context is to use FluentU, which  provides foreign language videos that native speakers actually watch, along with interactive subtitles, translations and even active learning tools like multimedia flashcards, quizzes and custom vocabulary lists. Use the content here to learn and practice new vocabula ry words using flashcards, as well as to access real-life contextual information about how the words are used and pronounced by watching videos!FluentU takes real-world videos like music videos, movie trailers, news and inspiring talks, and turns them into language learning experiences, as you can see here:FluentU App Browse Screen.FluentU has interactive captions that let you tap on any word to see an image, definition, audio and useful examples. Now native language content is within reach with interactive transcripts.Didnt catch something? Go back and listen again. Missed a word? Hover your mouse over the subtitles to instantly view definitions.Interactive transcript for Carlos Baute song.You can learn all the vocabulary in any video with FluentUs learn mode. Swipe left or right to see  more examples for the word you’re learning.FluentU Has Quizzes for Every VideoAnd FluentU always keeps track of vocabulary that you’re learning. It uses that vocab to give you a 100% personaliz ed experience by recommending videos and examples.Start using FluentU on the website with your computer or tablet  or, better yet,  download the FluentU app from  the iTunes store  or Google Play store.6. Use a dictionaryUse a dictionary to look up:Unknown words you read or hearTranslations for words  you want to learnHow to spell a wordHow to pronounce a wordYou can also use a dictionary to find grammatical information about new words.  Most dictionaries will tell you things like which preposition(s) or noun case(s) to use with a word and provide  sample phrases using the word.There are two different ways to access a dictionary:Print  dictionaries.  Find one that is made by a reputable company and used popularly. These are usually well-researched, accurate and thorough.Online dictionaries. These provide easy, fast opportunities to look up words and may  include features like audio pronunciation samples. However, you may find it frustrating to type in your foreign language, and it c an take some research to find the most  reliable and accurate online dictionary.You can also choose whether to use a bilingual or monolingual dictionary.  Bilingual dictionaries are the easiest way to learn new words. However, monolingual dictionaries often provide more grammatical information and examples of a word in context. It may be helpful to use a combination of both dictionaries, or seek out a bilingual dictionary that provides  thorough grammatical and contextual information.7.  Learn word partsOne of the most effective ways to improve your ability to predict the meaning of  new words is to study word partsâ€"the roots  and affixes that make up words.This process is less familiar to language learners than learning whole words and is best used after youve developed a substantial vocabulary of whole words. However, if done right, it can provide you with the capacity to guess the meaning of new words without looking them up, greatly increasing your comprehension of the languag e.Word parts include the stems  that give a word its general meaning, as well as affixes that modify the grammatical form or structure of the word and provide important information about its exact meaning.An example of a word stem in English is  -STRUCT- which means to build. Its the root in words like  structure and construct.The stem is also used in a wide variety of other words, including destruction, instructive and obstruct. Each word has a different meaning, but you can see how they all relate to a general sense of building.Affixes are also useful in predicting the meaning of a word. In English, these include prefixes like de- and non- as well as suffixes like -ment and tion.Knowing what these affixes mean can  help you understand that destruction is a noun (the suffix -tion tells you this) that means to tear something down (the opposite of building, as you can see from the prefix de-).This approach requires that you find sources for information about word parts in your target language. The book  Leveraging Your Russian with Roots, Prefixes and Suffixes  provides students of Russian with a thorough source of word parts to study.Online sources like Building Your Vocabulary: Prefixes  provide word parts to study in Spanish, and  lists of Greek and Latin roots  can help you learn these languages or learn English words derived from these languages. There are also many sources of information about Arabic word roots, which function slightly differently  but use the same general concept.8. Embrace memorization techniquesAs you use  the methods described above, you should make use of memorization techniques that will  help you remember new information. A few of the best methods include:The keyword technique. Make up a story using the  new word, the meaning of the word and a word in your native language that sounds similar. If you want to learn the Turkish word ev, which means house, you might think that it sounds like the English word every. Your story might be something like, Im in my house every day.Visualize and vocalize. When you learn a new word, take a moment to visualize  an image of the words meaning and say the word aloud.Use the word in your native language. Practice the new word not only in your target language but also in your native language. If youre learning  the Spanish word siempre, which means always, you might say things like, I siempre meet my friends for lunch on Thursdays.Make  gestures. Research  shows that the brain learns better with sensory inputs like physical actions. If youre learning the word for ball, try making a ball with your hands and pretending to throw it as you repeat the word aloud.Learning vocabulary takes practice and time, but it can be rewarding and fun and, with the right methods and techniques, you can speed up your learning enormously.As you learn, dont forget to look back on your notes or flashcards to remind yourself how much youve already learned.And remember to practice the new words you le arn in context by doing a general online search for articles with the word in them, writing stories, writing journal entries with the words or watching videos on FluentU.

LSAT Logic Games Sequencing Game Tutorial

LSAT Logic Games Sequencing Game Tutorial Those aspiring for law school understand that studying logic games are crucial to landing a score that will get you into the law program of your choice. Logic Games account for roughly 23% of your LSAT score, so knowing the ins and outs of this portion of the LSAT is imperative. What are we waiting for? Let’s jump into the details of logic games as well as some examples. What are Logic Games? The Logic Games are a section of the LSAT that requires analytical reasoning to solve problems that only provide a set of rules that may be used. Rather than memorizing information that must be used on this section, the logic games require the test taker to understand the structure of the information provided as well as make a logical conclusion about this information. This all sounds a bit more complicated that logic games really are once you understand the types of logic games to expect on the LSAT. Believe it or not, the logic games can actually be quite fun once you get the hang of them! In this post, we are going to walk through, step-by-step, on a sequencing logic game that you can find on the LSAC’s free June 2007 LSAT Practice Test: Passage: A company employee generates a series of five-digit product codes in accordance with the following rules: -The codes use the digits 0, 1, 2, 3, and 4, and no others. -Each digit occurs exactly once in any code. -The second digit has a value exactly twice that of the first digit. -The value of the third digit is less than the value of the fifth digit. Explanation: We know this is a sequencing game because the passage tells us that there are 5 digits and that there is some sort of sequence to these digits. We can draw this out as our game board: Next, we know we have 5 game pieces: 0, 1, 2, 3, and 4 we can draw these out to the left of our game board: The next rules says that each digit occurs exactly once, meaning we couldn’t place 0s (or any other numbers) across the entire game board. The third rule says that the second digit has a value exactly twice that of the first digit, so let’s draw this out: Let’s think about this rule for a moment and determine how many possibilities there are for the first two places on our game board for one number to be twice the other. We know immediately that the first spot cannot be 0, because twice of 0 is 0, and we cannot use the same number twice in the sequence. Next, we can try placing 1 in the first spot. Twice of 1 is 2. That would be a possibility. Same goes for 2 in the first spot, as twice of 2 is 4. We can now split our game board into 2 scenarios, where the first two spots are either 1 and 2 or 2 and 4 (and the remaining game pieces on the left of each potential game board: The last rule says that the value of the third digit is less than the value of the fifth digit. Let’s start with the first game board and write out all possibilities using the remaining game pieces, each starting with the sequence 1, 2: We can go ahead and do the same thing for our second game board, filing in the remaining 3 open slots with possibilities, each starting with 2, 4: Okay, so now we have made as many conclusions as possible using the set of rules given to us in the passage. We have 6 different possibilities of sequences that fit the rules. Now let’s try tackling a question: Question 1: If the last digit of an acceptable product code is 1, it must be true that the (A) first digit is 2 (B) second digit is 0 (C) third digit is 3 (D) fourth digit is 4 (E) fourth digit is 0 We know that there is only one possible sequence where the last digit is 1: Going through the answer choices, it becomes quite obvious there is only one correct answer based on our numbers: The final answer to this question is A) first digit is 2 You can find the remaining question explanations for this passage at 7Sage’s logic games explanations. As you can see, logic game questions do not need to be super complicated or intimidating. The best way to combat feeling overwhelmed by these questions is to draw out the rules, step by step, so that you can systematically go through each question following the passage.

The Fundamental Units of Measurement in Chemistry

The Fundamental Units of Measurement in ChemistryThe electron cloud definition of the elementary particle, the 'elementary particles', includes all of the protons, neutrons, and electrons in the Earth's atmosphere. It can be seen when you look at the sun, but when a helium atom has more than one proton, it's an ion. The next level in the elemental classification system is the carbon atom, which has three protons.A carbon atom has three protons because it's made up of the same three protons that make up an oxygen atom, plus one electron. An atom with four protons, for example, has four different atoms which have been arranged in a different way.To determine the atomic number of a substance, all you need to do is count the number of protons in the atom. This is usually done by observing how light comes through the substance. If you want to know what chemical element a substance is, you have to add the atomic number of the atoms of the elements, including the hydrogen atoms, and then su btract the number of electrons.The common aspect between all these different units is the basic principle of quantum chemistry, which is based on the same concept. In quantum chemistry, particles can be considered as wave forms in space, and the units of measurement are the frequency of the waves and the space in which they exist.The electron cloud definition is a standard unit of measure in all fields of science, and therefore it's the easiest way to relate things to each other. For example, for a problem involving gold, you need to figure out how much of each element it contains, or just estimate it based on the element number in its molecular formula.So, if you learn the cloud definition and the basic units of measurement, you're ready to use them in any situation. And the best thing about the cloud definition is that it's so easy to remember.Chemistry doesn't really have to be difficult to learn, but sometimes it can be a little bit confusing. If you know the cloud definition, y ou can make things much easier on yourself, and it will help you make sense of what's going on.

Convert To Mixed Number

Convert To Mixed Number Convert to mixed number is a number which is written in the form of a whole number and a fraction. Mixed number is in the form of combination of whole number and a proper fraction. In everyday use, mixed numbers are better to understand. There are various types of fractions. They are proper fraction, improper fraction and mixed number. Improper fraction can be converted into mixed number but a proper fraction cannot be converted. Improper fraction has numerator larger than it denominator. In mathematics improper fractions are better than a mixed number when used in problem solving. Example 1:Write the fraction 22/7 as a mixed number Solution: To convert improper fraction into mixed number we perform division method (Remember that we are not dividing the fraction) Take 22 divide by 7, find out the quotient and remainder When we divide 22 / 7 we get quotient = 3 and remainder = 1 Therefore, 22/7 = 3 1/7 is the mixed number. Example 2: The winner of class president got 3/8 of the vote. If 200 students voted, how many students voted for the winner? Solution: Vote he got = 5/8 Number of students = 100 To find the number of students voted for the winner, multiply the fraction of the vote he got and the number of students voted Therefore, 5/8 X 100 = 500/8 = 125/2 Take 125 divide by 4, find out the quotient and remainder We would get quotient = 31 and remainder = 1. Therefore, 250/4 = 31 From the above examples we understood method of converting to mixed fractions.
