just you need understanding ALL processes and theory ,for example - so my opinion good luck bye
I agree with @jhonny9, if you understand the theory, everything works out. And remember, basically all calculations are derived from these basic formula. |dw:1339423389890:dw| oops, sorry at the bottom of the moles is volume. This is the basic equations for chemistry. (excluding heat etc)
understanding concepts are the most important. Memorising completely is not a solution.
A great deal of chemistry simply requires memorization. This should not come as a surpirse: chemistry is a load of concepts build on top of a great big pile of observations and facts. If you are not familiar with the facts -- if they are not at your fingertips -- the concepts and theories won't make enough sense to become second nature. So I disagree somewhat with the Zeitgeist: you DO need to memorize quite a lot of things to become good at chemistry. ON TOP of that, you need to become familiar with the ideas and methods that will make sense of your memorized facts. Do not neglect either. And how do you become good at both? The same way you'd become good at baseball, or baseball trivia: practice, practice, practice. Do every problem in the back of the chapter. Do problems from other books. Do problems your teacher recommends, and more besides. Make some up yourself. And: make use of the fact that the single strongest learning experience is taking a test. (You can look this up in the professional literature on education, if you like. There was even a NYT story on it some time ago.) Taking a test is a much better learning experience -- will solidify your knowledge -- far better than listening to a lecture, watching a demonstration, talking things over with your friends, or even doing a problem in the book, if you have access to the book and/or an answer key. When you are straining your mind and your memory, trying to reproduce a chain of logic you once read or heard, trying to make sense of a problem without any training wheels or assistance -- this is when your knowledge solidifies and becomes permanent. So...practice taking tests as much as possible. After you read a chapter or section, jump straight to the problems for that section or chapter and do half of them WITHOUT allowing yourself to look back at the chapter. Then re-read, and find your mistakes, and then do the other half the same way. Make up practice tests for yourself to practice for a real test, or make them up for your buddy and have him make them up for you. You'll find just making up a test is good review and practice itself, and then taking it will be useful, too. Even while you're sitting in lecture, try making up a practice test problem for yourself every 10 minutes or so on what you just heard. Imagine yourself as the teacher: how could I design a problem to test understanding of what was just said? It doesn't have to be a problem with lots of math -- in fact, the less math, the better the problem usually. But it can't just be a definition or fill-in-the-blank problem, either, at least not all the time. It needs to be a problem that doesn't directly ask for what the teacher aid, but which asks for something that can't be found without using what the teacher just said. For example, the teacher says "the empirical formula of ionic compounds is determined by charge balance -- the charge on the cations must balance the charge on the anions." You don't want to always imagine a test problem like "Q: What determines the empirical formula of an ionic compound? A: Charge balance." That's just simply repeating what the instructor said. A monkey or tape recorder could do that. You want a question like "If I were to make a compound from Na+ and Cl- ions, how would I figure out the empirical formula? " or "If I had a compound make from Na+ cations and some fluoride anions, and the empirical formula was NaF, how could I deduce the charge on the fluoride anions?" These questions don't just repeat what the instructor said, but you can't answer them without knowing what the instructor said. The biggest secret of education is that teachers don't really teach. Students only learn when they teach themselves. The most your "teacher" can do is provide you with the facts and ideas, arranged in an orderly way, and give you measurment devices (tests) to see whether you are doing a good job teaching yourself. But if you are just waiting for someone to magically fill your head with knowledge -- it won't happen. You must do it yourself.
Thanks for all of your tips :) I will become very good in Chemistry soon :)
