What preparations should be made for the first round review of senior high school chemistry? What should we pay attention to in the first round of chemistry review? Ask experienced brothers and sisters for help. The best way is to find a tutor ~ ~ and an experienced tutor, which will get twice the result with half the effort.

However, I can talk about my own experience.

Chemistry is a partial science, and there are many things to remember. Let's not talk about conceptual things. We must recite it by ourselves. The first round of review is based on basic knowledge, so what should be remembered should be remembered, and it is skillful to remember things. You can try this skill with the skill of remembering physics. They are similar. You should study the basic knowledge of chemistry in categories, and I believe that review is also classified, such as inorganic matter, oxygen, C, N and so on. Chemical experiment, storage, extraction, etc. ; Organic matter, CH4, including the experiment of organic matter, these are the big questions that must be tested in the college entrance examination. You can look at the college entrance examination papers, and then classify them to see which parts have high scores, and focus on review. The teacher speaks very quickly in a round of review, and many things are copied once, so the teacher won't say so much about the details, so there will be a lot of practice, just practice more. I suggest you focus on the required textbooks, which is the focus of the exam. If you have time and money, you can buy a "study note" with a red cover. I forget which one belongs to our club. I learned a lot from it from the beginning. You can get more information, practice more and do more things that others don't pay attention to, and you will get higher scores than others. The conclusion at the end of each chapter is very important. You should read it carefully and ponder it carefully, because it tells you what you have learned and what you should learn.

The last trick, the ultimate trick to kill the exam together in a short time, is to take the college entrance examination papers of the previous two years, carefully analyze each question, divide the categories, and then find a topic to practice specifically for this category. This is a trick to improve the score in a short time and cram for the Buddha's feet before the college entrance examination. If I remember correctly, there are several big questions in the People's Education Edition.

1, the experimental questions include purification, proving the existence of something, removing impurities, etc., mainly the matters needing attention in the use of experimental instruments, experimental process, calculation, etc.

I don't know how to do organic matter test now. If it is a big question, it is generally more difficult. It is difficult to know the content of compulsory five.

3, electronic transfer, the amount of materials, there are many calculations for this kind of problem, we should pay attention to some concepts, and the calculation of electronic transfer must be there. However, all the calculations are special numbers. If your calculation result is not a special number, you must have done something wrong. Chemical calculation is special, which can be used as a ready-made check.

The new topic is the so-called selling dog meat by hanging sheep's head. Give a lot of new terms, new technologies and new processes, all of which are nonsense. As long as you have a mind, analyze it: purpose, process and result. It's all familiar parts, don't worry. Some people just don't do it when they see such a long message. Actually, this is a sub-topic.

5. The problem of ion concentration is also very difficult. At first, I got high marks, but everyone is not high on this kind of questions. If you practice more, you will win.

That's all I can think of at present If you don't understand, you can continue to ask.
