Organic Chemistry - Nomenclature the Organic Chemistry Tutor Ionic

Organic Chemistry - Nomenclature the Organic Chemistry Tutor IonicWhat is the nomenclature in Organic Chemistry? If you are a Chemist, you probably will know the answer to this question. But if you are not, then here is a quick introduction of it. Nomenclature is the system by which names are assigned to the properties and features of objects.The system has been used since the 1930s in studying complex organic compounds, like peptides, aromatic amines, nitriles, etc. There are certain characteristics of these compounds which, once observed, give out the name of the compound, such as its reactivity or stability. For example, amide A has the characteristic 'analogous with', 'same with', 'similar to', 'comparable to', 'considered equivalent to', etc.So the organic chemistry tutor ionic or rubric has several functions in chemistry, which we will discuss later. In order to become a proficient in organic chemistry, you need to have a good grasp of the nomenclature system. There are some on line course providers that will explain the entire procedure to you in layman's terms, which would definitely help you if you are starting your online study.So what is nomenclature the organic chemistry tutor ionic? In organic chemistry, nomenclature is nothing but the common designation of a property of a compound. So, let us learn more about the nomenclature.First of all, when we talk about properties, what exactly are we talking about? We may speak about, for example, the property of being alkaline. However, the term 'alkaline' means different things in different fields. The property 'being alkaline' is often called the pH scale, while other properties may be called the 'alkalinity' of a molecule.Secondly, what is a rubric? This is an element that is bonded to an atomic nucleus to define an atom's particular composition. Rubric chemistry also refers to the rubric code of a compound. This Rubric code is a four-digit number that is assigned to each and every element in a compound.T hirdly, what is nomenclature the organic chemistry tutor ionic? In organic chemistry, there are four elements that we need to know, namely the nuclide (group), the alloy (property), the organic group and the molecular formula.The chemical formula is the key to success in organic chemistry, because it is the best indicator for the behavior of a compound. It indicates the exact chemical makeup of the compound, including the number of atoms and the type of bonding that takes place between the atoms of the compound. For this reason, it is always important to check the chemical formula of a compound before you are going to use it for research.

American University Professor Gerald Watkins Chadwick Made A Quantum Leap In Chemistry

American University Professor Gerald Watkins Chadwick Made A Quantum Leap In ChemistryIn Chemistry, American University professor Gerald Watkins Chadwick contributed to chemistry by defining the universal atom. Chadwick was a Cambridge University mathematician and philosopher. His contribution in science began in 1907, when he published his 'Elementary Principles of Chemistry'.Chadwick's achievement was similar to other scientists whose first contributions are not known. In other fields, such as in medicine, astronomy or law, some scientist who did something groundbreaking do not get their achievements recognised.The process that Chadwick used to define the atomic nucleus of a compound is the same method that astronomers use to describe the atomic structure of a planet or star. The atomic nuclei of atoms are classified in terms of their 'charge' or their 'mass'. This classification is very important for atomic theory because it tells scientists what the 'weight'thickness' of an atom is, where mass is measured in Joules.Before Chadwick's work, physicists could only measure mass. The method of weightless atoms had no place in their studies. It was, therefore, up to Chadwick to devise a way to see whether molecules were truly being weighed down by a mass or if they simply were being assessed by the properties of an observer. He used the microscope to enable him to check the results.The method that Chadwick used to describe 'natural' atoms is still used today. Chadwick worked on the idea that molecules can exist in three states - metallic, liquid and gas. They can also exist in different molecular masses.Chadwick's contributions to chemistry were considered revolutionary at the time. While they have since been adopted and refined, the key idea that Chadwick worked with has remained with us for hundreds of years. The atomic weights of atoms, combined with the fact that they are the closest thing to a precise measurement of the mass and density, means that there are many ways to derive specific values of mass and density for different atoms. Chadwick would never have imagined the possibility of a vacuum.Chadwick was instrumental in establishing the principles of modern physics as we know it today. His contributions are considered vital to the continued progress of physics and chemistry.

Antiderivative of X

Antiderivative of X Anti-derivatives is the reverse or opposite of derivatives. Here the function given is x and the exponent to which the variable is raised is 1. The power rule is used to find the anti-derivative for any function which contains a variable raised to an exponent.According to the power rule any function which has the variable raised to the power n is written as xn has theanti-derivative = xn dx= x(n+1)/ (n+1) + c.Hence the anti- derivative of the function x is 1x2/2. Example 1: Find the anti-derivative of the function f(x) = x + 6x3 Here the given function is f(x) = x + 6x3 The anti-derivative of x is 1/2 * x2 Using the power rule, the anti-derivative of 6x3 has to be found. Power rule states that anti-derivative of xn = xn dx= x(n+1)/ (n+1) + c Therefore, the anti-derivative of 6x3 is 6x4/4. Hence F(x) = 1x2/2 + 3x4/2 + c Example 2: Find the anti-derivative of the function f(x) = 15 x. Here the given function is f(x) = 15 - 3x. The anti-derivative of x is 1/2 x2 Using the power rule, the anti-derivative of 15 has to be found. Power rule states that anti-derivative of xn = xn dx= x(n+1)/ (n+1) + c 15 can be written as 15 x0. Therefore, the anti-derivative of 15 x0 is 15x1 Hence F(x) = 15 x -x2/2 + c

4 Confusing Grammar Rules Cleared Up

4 Confusing Grammar Rules Cleared Up Confusing grammar rules frequent the English language. Whether youve been composing essays in college for a couple of years or are just entering high school English, there are a handful of common errors that can trip you up. Correct grammar is essential for effective communication, both spoken and written, so it is important to brush up on these details every now and then to ensure you are showcasing your best potential to teachers, peers, and future employers. While there are numerous intricacies to the English language, lets take a look at four commonly confused grammar rules 1. You and me vs. You and I This is the one that you may often hear people changing as they speak. There is a misunderstanding that it is always wrong to say you and me, when in fact, you and me has its own unique usage which differs from that of you and I. In short, you and I is a subject pronoun; you can think of it as we. For example, You and I went to the market for fresh bread. You and I can be substituted for we without any problem (We went to the market for fresh bread.). On the other hand, you and me is an object pronoun; you can think of it as us. For example, He bought this fresh bread for you and me. You and me can be substituted for us (He bought this fresh bread for us.). To help you decide whether to use you and me or you and I, plug in we or us, respectively, and see which one fits. [RELATED: Study Strategies for Reading] 2. Lie vs. Lay It is easy to remember that one definition of lie is to tell something that is untrue. Of course, lie can also mean to recline, as in lie down on the couch. The chief difference between lie and lay is that lay requires a direct object, while lie does not. For example, in the sentence, the bird is laying eggs, the eggs are the direct objects being lain. Now, think about the sentence, the mother lays the baby on the changing table. What is the direct object? If you guessed it was the baby, you are correct. 3. I.e. vs. e.g. I.e. and e.g. are handy abbreviations for the purpose of clarification, both of which come from Latin. But, contrary to popular belief, these terms should not be used interchangeably. I.e. means in other words, while e.g. means for example. Here is an illustration of how to use them properly: -Only 25% of test takers passed the test the first time i.e., most students failed the test on their first attempt. -Our caf offers non-dairy substitutes e.g., coconut, almond, and soy milk for use in coffee beverages. An easy way to remember when to use i.e. and e.g. is by the letter they each start with. Think of the i in i.e. as in (in other words) and the e in e.g. as example (for example). You will never confuse them again! 4. Good vs. well You probably already know the difference between good and well when they act as nouns (a manufactured good, a water-filled well). But what about their usage in other contexts? In short, good is an adjective; it describes a noun (a good vacation, a good idea). Well is an adverb; it describes the way in which an action is done (he plays the clarinet well). It may seem complicated with phrases like a well written story and a well articulated point. However, we can look at these phrases and see that well is still acting as an adverb. Written and articulated are the adjectives. Now is the perfect time to become more familiar with English grammar rules, if you have not already. Employing proper grammar will be extremely beneficial not just in your time as a student, but in college applications, grad school admissions, and job hunting down the line. A great way to keep these sharpened skills on your mind (in addition to studying) is simply to read and write on a regular basis with a little practice, these rules, and others, are more than likely to stick with you!

The Best Tips For Buying Maths Equipment

The Best Tips For Buying Maths Equipment Maths: How To Choose Your Basic Equipment? ChaptersWhat Is The Essential Maths Equipment Needed For The Maths ClassroomMaths Equipment For SchoolThe back to a school shopping list is a long one, especially with the ever-growing number of subjects in the education program. This curriculum development has meant that now not only do you have to provide the basic school supply list for students. But you also have to add to this special equipment for classes like arts crafts (art supplies like a sketchbook, coloured pencils, paints, an easel and crayons) or get costumes for a role play or active play in the school theatre.The school math curriculum alone requires a large number of back to school supplies. School shopping for a mathematics course alone can include a scientific calculator (depending on the grade level for lower grade a basic calculator is fine), textbooks, post it, paper clips, a binder, rulers, markers, highlighters, sharpeners, an eraser not to mention the basics like pens and pencils. This excludes any real moder n conveniences and high ticket items.Despite how long the school supplies list happens to be. It is the parent's job to guide their children and provide them with all of the tools which create the opportunity to perform at their best. It is the child's job to take that opportunity and those tools and turn them into success. Student achievement provides a flash opening to better privileges, university placements, higher paid jobs and happier life overall. Knowing you have done your best and had the opportunity to demonstrate that it is a rewarding feeling that is hard to beat.So while the ever-growing school supply list could be fast multiplying into school supply lists. Lack of study/office supplies should not stand in the way of Student learning, and it should not be the thing to disrupt the learning environment. For example to try to find or borrow equipment in the middle of classroom activities.For students, mathematics courses can be a challenge, times tables, counting, dividing , multiplying, calculus, fractions, algebra, addition and subtraction are just the tips of the iceberg when it comes to maths courses and student development.Looking at high school math, let's consider which equipment is needed to excel on the course.

The good thing is that if you ask your math teacher, they will be able to give you either a math worksheet with the lesson plans for the coming year so that you can research the equipment required. Or if they are more organised, they will provide you with a math class supply list.You don’t have to wait to ask for this list, as a core subject, the math curriculum doesn’t change much. So teachers will be able to advise you on what will be useful for your entire high school or college attendance. However, if you prefer to go year by year, you can ask teachers at school open evenings, parents meetings, write notes to the teacher or arrange an end of year meeting with the teachers you would like to talk to.If you have missed the opportunity to speak to the educators at school or don’t have the time for that, however, then the below list will be very useful to get you started.Discover a maths tutor that can help you through le arning maths here.The back to a school shopping list is a long one. Photo Source: UnsplashMaths Equipment For SchoolCalculatorIt may surprise you to find out that there are many types of calculators in the market. Each different kind of calculator is meant for a different job. The simple calculator in kindergarten may be the same as the one used in primary school, but it most certainly will change when you get to high school, college and university.While you can do the more complex calculations on a basic calculator, it really serves you well to invest in a calculator that will meet your needs. The whole point of a calculator, after all, is to help you with mathematics.Simple Calculator - This is the Primary school level calculator which specialises in subtraction, addition, multiplication and division.Scientific Calculator â€" The scientific calculator can do everything that the simple calculator can do. It is also able to perform much more complex equations and calculations. You c an perform calculations like Pre-Algebra,  Algebra, Precalculus,  Calculus, Geometric, Fractions, Equations, Algebraic, Competency, Trigonometry, exponents and logarithms. This is a high school to university level calculator. This is the most useful calculator and the one that makes the best investment for a math studentGraphing Calculator - The Graphing calculator can do everything that the simple calculator (like Pre-Algebra and Precalculus) and the scientific calculator can do (like Geometry,  Trigonometry and algebraic calculations). It also has the added function of being able to perform calculations of integral calculus and matrices. And when you type something in to be calculated you will see a graph of it in the graphing calculator screen. This is a calculator for college and university level students.guide their children and provide them with all of the tools which create the opportunity to perform at their best. Photo Source: UnsplashGeometric Measuring  ToolsGeometry is a type of maths that works out the areas and diameters of 2-D shapes and figures as well as points, lines and angles.The four important tools of geometryRuler - A ruler is a tool that we all know and love because despite its simplicity we can not live without it if we want to draw straight lines. It also is used to measure distances. One with 12 inches and 30 cm will be fine for any math class no matter what grade level the student is in.Compass - This a tool used to draw circles or arcs of circles. It is a metal tool set in a v shape that has a point on one tip and a hole to hold a pencil on the other.Protractor â€" Not too dissimilar to the ruler except this is set in a semi-circular shape with measurements of angles from 0 to 180 degrees.  When you lay, the protector on the angle that you want to measure you will be able to easily work out the degrees.PaperWhether for maths or other classes, while you are studying, you are going to need some paper. In maths, you will use this for class notes, calculations and general study.Rough Note Paper - This paper can be from recycled paper found on paper bags, draft paper, receipts, the back off printed throwaways, or you can buy it. The Post it is a fancy version of this kind of paper.Graph Paper â€" This paper as it sounds is made up of lines that cross to create small squares it is often used in maths as it makes it easier to write out equations, draw graphs and design charts.CarriersNow that you have all of your maths kits don’t forget to buy something to carry it in.A pencil case â€" The pencil case allows you to carry everything you need and doesn’t take up too much space on your desk. A great way to organise your kit since you will have lots of different classes. Is to have a general pencil case with your basic stationery in it, then have class specific pencil cases that have the tools for your specific courses.backpacks â€" The backpack is another great tool for organising yourself for school. Buy one that has enough space for all of your books and other stuff. Buy a smaller bag for your gym kit if you have gym classes. As dirty trainers will tear and mess up homework and coursework in your main rucksack. It is advisable to have separate bags. If you do swimming or art too. As wet paint and a damp swimming costume will ruin anything in your backpack.Essential Maths Equipment Needed For The Maths Classroom. Photo Source: UnsplashOther Basic stationeryPens â€" gel pens are my favourite as they give a smooth writing experience. They also have a padded finger area. But pens are a personal choice.Pencils â€" this is very important as it is better to use pencils over pens in math as you will likely need to erase things lot as you update your work.Eraser â€" as mentioned above they need to keep work up to date and correct pencil mark mistakes. (liquid erasers like tipex are also useful for mistakes made with pens.)Highlighters / coloured pencils â€" help to highlight your work and create eas y to read sections. You can also use different coloured pens for this reason.Notebook, planner â€" Notebooks are essential for taking notes in class and for your own thoughts on the course and the work. Planners, however, are great for planning out your workload, homework, and your time table.Being a student is hard work, even the math equipment you have to invest in is a long list. However, the reality is that while the tools are useful, it is really you that brings success to your student life. However, you approach this part of your life to remember that learning is a lifelong journey.If you are looking for back to school kit ideas for young kids, check out the math supplies for kids blog!

To Learn More Keep Testing Yourself

To Learn More Keep Testing Yourself It turns out that taking a test isnt just a teachers easy way of finding out where students stand or forcing them to read a chapter in a textbook. Testing might actually boost student learning and improve memory retention, according to a report cited in the New York Times. The report, published in the journal Science, concluded that students who read a passage and were then tested a week later on what they read retained about 50% more of the information than students who used other, common study methods. The other methods students used were repeatedly studying the material cramming and creating detailed diagrams of the information, connecting it all together in students own words and thoughts. Many teachers believe that the latter method is an effective method for studying because it forces students to create connections among information points. These two methods can give students the false belief that they know the information better than they actually do, according to the report. The results surprised many cognitive psychologists and other educational scientists who long believed that creating connections among information was the best method of learning. For the test, researchers placed 200 college students in two experiments, both experiments had them read several passages about scientific subjects, like the digestive system or muscle tissues. In the first experiment, students were separated into four groups. The first simply read the passage in a five-minute session, the second read it in four separate, five-minute intervals, the third engaged in concept mapping, creating hand-drawn diagrams and bubbles to link the information they read in their own, personally-organized fashion, the fourth group took a retrieval practice test, where they free wrote every thing they remembered for 10 minutes. This group then reread the passage and took a second retrieval practice test. All four groups were than given a short-answer test a week later, assessing how much of the information they could recall and the logical conclusions they could create about what they had read. The students in the fourth group, who performed the retrieval practice tests, outperformed all other groups. The second experiment focused only on concept mapping and retrieval practice testing. Students were separated into two groups. One group created a concept map, and the other group took tests, asking them to recall information. Similar to the first experiments results, the students who took retrieval tests recalled more information a week later, even when they were asked to draw a concept map from memory. Cognitive psychologists cannot exactly pinpoint what causes these results. But, many believe its because taking preliminary tests gives our brains practice. Our brains can create contextual cues and patterns for remembering information during the preliminary tests, making recall easier because the brain can then remember the cues and the patterns, which can then lead to remembering the information itself. Then once the second test is administered, our brains can easily recall these patterns or context cues because they were previously in our minds. These results have practical applications as many teachers administer quizzes or practice tests before larger, more-weighted exams, or even when teachers administer mid-term exams then final exams. Students who were previously tested on material will be able to remember it more effectively when they are tested again.

The Little-Known Difficulties Of Playing Beginner Guitars

The Little-Known Difficulties Of Playing Beginner Guitars Suzy S. If youre in the market for a guitar, youve likely seen beginner models and packages offered. But are they worth it? Find out in this guest post by Austin, TX teacher  Samuel B... Recently some of my beginner students have requested shopping tips for more advanced models of guitars. Though my familiarity with standard models for various genres is considerable, I dont train aspiring musicians to master one specific genre. Although jazz sounds best when played on a hollow-bodied electric with f holes on either side of the strings (just as blues-rock is played best on a Fender Stratocaster, electric Chicago-based blues on its cousin the Telecaster, and so forth), I dont recommend that you purchase one of these models for the reason cited above. Beginners frequently learn to play “beginner” guitar models (miniature instruments made by obscure companies). If youre a beginner, I recommend that your brand of purchase instead be recognizable. It need not be brand new or first-hand, but it should be a model of some note. Martin is one name of repute. So are Fender, Yamaha, Washburn, and Epiphone. These models are known not only for their sound, but for their relatively uncomplicated maintenance. While inexpensive, the beginner guitar models you see have multiple drawbacks: Beginner guitars produce a poor sound My first acoustic guitar (a “beginner” model) did. This is not an issue when youre being introduced to the instrument, but will likely become one once you reach an understanding of your potential as a musician. You want an instrument that broadcasts (not simply delivers) your sound. You might as well start with one. Beginner guitars are generally more difficult to re-string than their mainstream counterparts Im remembering several bridge-related hiccups with my first electric (another obscure model), some of which required the use of Allen wrenches. At one point, I even lost a weak tuning peg on it and had to resort to an ill-fitting replacement during the rest of the instruments shelf life. If memory serves, the pickup itself wobbled as it appeared to have been poorly fastened. Recognizable Plug-In Acoustics Give You the Most Options I can only recommend the genre-specific models listed at the beginning of the article if youve made your desire to master only one technique unequivocal. Otherwise, recognizable plug-in acoustics give you the most leverage, whatever your aspiration be it to perform, record, lead singing, teach singing, or even embark on a musicological endeavor like collecting and learning little-known folk songs. Theyre durable, sonically pleasing, and are proper equipment for anything from Kum Ba Ya around a campfire to a CSNY reunion show at the Hollywood Bowl in that the simple element of electricity (or lack thereof) determines the role theyll play. So, What Type of Guitar Should Beginners Purchase? As a performer, my act falls within the singer-songwriter category, which typically involves the use of an acoustic guitar plugged into a sound system. I own two: a Yamaha (purchased from some former housemates for less than $100) and a Takamine (which I obtained roughly 10 years ago upon trading in both my first black electric model and my Telecaster imitation model I may have even sacrificed an inexpensive amplifier or two in the exchange as well). My Takamine has been a faithful sidekick during innumerable sets at local coffeehouses here in Austin. Its also one of the most recognizable acoustic-electric brand names. I always have it in my lap when I teach and I believe it to be among the top user-friendly models; it has proved itself the most versatile and reliable guitar Ive ever owned or played. It sounds cleaner and is more robust than any other model familiar to me. Its durability has allowed me to serve the multiple roles of performer, teacher, and independent recording artist. I can also maintain my relatively low-consumption lifestyle the backpack straps on its case (a separate purchase) make for easy transport on bike, bus, and even plane. Be Patient And Open-Minded While Shopping The best shopping advice, of course, is to explore multiple options. Despite my mainstream-oriented advice about the brands, I recommend that you seek your model in a pawn shop or locally-owned music store, as these outlets tend to have better deals than large chains. You might even have luck on Craigslist. I also recommend that you compare prices as much as possible. Just as you need a reliable vehicle to carry you long distances, you need a sturdy, versatile, and aurally-attractive instrument to accompany the ongoing development of your musical knowledge and enthusiasms â€" preferably from the very start. That way, you wont have to anticipate replacing your instrument down the line. Samuel B. teaches beginner  guitar lessons in Austin, TX.
