How to learn chemistry in high school, the level can be the same as you, and I basically haven t tak

Listen to the teacher, be sure to memorize all the equations, memorize the reaction principle, and then it's OK.

Then start from scratch and study hard.

Preview the basics.

Identify concepts. Review the questions carefully.

Answer the questions carefully. Summarize in a timely manner.

Look for the cause of the error.

Chemistry is not difficult, you have to believe that you can learn it well.

It is a science subject, so you can't relax on its comprehensive and systematic learning, in addition, you must also have enough exercises to actually apply the knowledge we have learned, and attribute them to our own knowledge structure, which may be difficult at first, but we must insist on summarizing and summarizing the knowledge points by ourselves, and in addition, we must have our own characteristics, which must be helpful to our own memory and understanding.

Chemical equilibrium, redox reactions, organic chemistry, ion equations, heat of combustion calculations, galvanic cells and electrolytic cells should be the focus of the sections. I'm telling you, reviewing chemistry is actually quite simple. Here's how I did it, and you can try it.

First, for inference questions, you need to organize the charts, for example, sodium and sodium compounds, write down various sodium compounds, and then think about how to react, what conditions, reaction phenomena, the color of each substance, write down these equations, it is best to write them silently, and then compare them with the book if you can't, so that you can memorize them very firmly. Second, for chemical equations, common redox reaction equations need to be memorized, that is, the dictation mentioned before, and it is best to write all of them silently every time they review or when they are involved. Many of the chemical equations in the college entrance examination are in books, and one question will involve unfamiliar equations that need to be balanced.

Third, chemical balance is the focus, which requires you to lay a good foundation and know how the balance will move under what circumstances, and it is best to sort it out. This type of question is always changing, so it's good to know the basics. Fourth, galvanic cells and electrolytic cells also require you to understand the cathode and anode, and then memorize some common galvanic cell equations, and electrolytic equations are also memorized.

Fifth, the heat of combustion, which is simple, knows how to make the energy equation that needs to be calculated, and it is enough. Sixth, for calculation problems, it is also necessary to calculate on the premise of being familiar with chemical equations. So in general, you need to organize your thoughts, organize your thinking about solving the questions, and lay a good foundation.

If you have anything to ask, come to me.

Chemical balance, redox, and organic chemistry should be the more important parts. The Organic Chemistry Society will always produce experimental questions, which account for a lot of points; Redox appears in the last calculation, which is not uncritical; The content of the fill-in-the-blank multiple-choice test is more miscellaneous, and nothing is the largest score, but it is foolish to think that chemical balance is rare, and it is not easy to understand it thoroughly.

The region is different, the test is not the same, and you should also remember to read the electives, we are learning the material structure, I don't know what you have learned. The energy change of chemical reaction is generally in the position of the first or second major questions, which is relatively simple, but very important. And then there is the comparison of ion concentrations or something.

The chemical process will definitely occupy a big topic, and the general test is more comprehensive, such as what to write chemical equations, the properties of various metals and non-metals, and so on. Choose to fill in the blanks and generally test the first few test foundations, such as what clean energy material properties and the like, and the fifth and sixth choices are generally tested and calculated. I suggest you still ask the teacher, the test is not exactly the same in different regions, I said according to the situation in Shandong.

There are more chemistry test memorizations, it is recommended to find this question, one set a day, stick to it, it will definitely be effective.

To put it simply, there are two key points in learning chemistry:

1. Construct an independent knowledge framework, i.e., trunk and branches.

2. Chemical language: Chemistry is a natural discipline, including the classification of substances, along with the gradual deepening of the concept, the chemical language should also be gradually deepened, such as the most basic chemical equations, from redox to periodic law.

My chemistry was suddenly enlightened after a week of frenzied work on questions in the second semester of my third year of high school, and my score suddenly went from a score of more than 95 points to a score of more than 95, and I never came down again. I always tell my child about it, and he always scoffs at me when he knows what I'm saying is true, and I can't do anything about it. I was a high school student more than 20 years ago, won a national physics competition, and now I am engaged in chemistry research.

A few days ago, I saw high school chemistry exercises, especially the organic chemistry part, my estimation is: even the front-line teachers in high school may not understand the mystery of the four major spectra, especially the mass spectrum and nuclear magnetic spectrum, because this is indeed the synthetic judgment center of organic chemistry, I went to study abroad, and I only thoroughly understood it after reading the spectrum every day, and now there are special readers in the world who judge the molecular structure through the spectrum, and the ** of each spectrum reads is: 2-5 US dollars.

Is it difficult for today's middle school students and teachers to have million-dollar MRI machines as teaching aids? I really don't understand why it's so hard to learn high school chemistry? Science is quite interesting, but I really don't want you to listen to other people's blind summing up experience, but you still have to listen to your own inner voice!

Got it? Think for yourself, there will be many problems in the future, all of them are very important!

Chemistry is a liberal arts subject in science, which is to rely on the back, followed by understanding, and the basis of memorization is to devote yourself to class and carefully understand what the teacher said. Chemistry is not like mathematics, only the brain is good, you must memorize more!

Chemistry in high school is actually still a little difficult, this subject is very cohesive, the foundation of junior high school is very important, if the foundation of junior high school is not good, then high school chemistry will be very difficult.

Moreover, there are a lot of knowledge points that must be memorized in this subject, and there are also a lot of knowledge that need to be expanded and understood by yourself.

There is a part of the interest in the study of chemistry, because it is composed of experiments and theories, and the two are mutually reinforcing, such as the imitation fruit is not interested in the reaction between substances, it will also hinder the learning of chemistry.

I think it's not that difficult to do in high school chemistry, but the reason why you don't think it will be is that, first, you don't understand some of the content fundamentally, and second, the more you don't understand it, the more difficult it is.

Workaround:

1. Read the textbook twice! Read it carefully, read every sentence thoroughly, and figure out the exercises after class.

When you're done, look at the periodic table and wonder what are the properties of each group? How are the electrons arranged in each period? What are the properties of each element? And so on and so forth. It is no exaggeration to say that a periodic table encompasses all of chemistry!
