How to study chemistry? Chemistry is dead and only needs to be memorized?

1. Pay attention to listening to lectures in class and review them in time after class. The acceptance of new knowledge and the cultivation of chemistry ability are mainly carried out in the classroom, so it is necessary to pay attention to the learning efficiency in the class and seek the correct learning method. During class, you should closely follow the teacher's ideas, actively think about the following steps, and compare your own problem-solving ideas with what the teacher said.

In particular, it is necessary to grasp the learning of basic knowledge and basic skills, and review them in a timely manner after class without leaving any doubts. First of all, it is necessary to recall the knowledge points taught by the teacher before doing various exercises, correctly grasp the reasoning process of various formulas, and try to recall as much as possible without using the act of turning the book immediately if it is not clear. Conscientiously and independently complete homework, diligent thinking, in a sense, should not cause a learning style that does not understand that is asked, for some topics due to their own unclear thinking, difficult to solve for a while, should let yourself calm down and seriously analyze the topic, try to solve it yourself.

In each stage of learning, it is necessary to sort out and summarize the points, lines, and surfaces of knowledge to combine and weave them into a knowledge network and incorporate them into their own knowledge system. 2. Do more questions appropriately and develop good problem-solving habits. If you want to learn chemistry well, it is inevitable to do more questions, and be familiar with the solution ideas of various types of questions.

At the beginning, you should start with the basic questions, take the exercises in the textbook as the standard, practice repeatedly to lay a good foundation, and then find some extracurricular exercises to help you develop ideas, improve your analysis and solving skills, and master the general rules of problem solving. For some easy-to-make questions, you can prepare a set of mistakes, write out your own solution ideas and the correct solution process, and compare the two to find out your mistakes, so as to correct them in time. In normal times, it is necessary to develop good problem-solving habits.

Let your energy be highly concentrated, so that your brain is excited, your mind is quick, you can get into the best shape, and you can use it freely in exams. Practice has proved that when it comes to critical times, the problem-solving habits you show are no different from your usual practice.

If you are casual, careless, careless, etc., you are often fully exposed in the big exam, so it is very important to develop a good habit of solving problems in ordinary times.

The most important thing in chemistry is to remember the properties of each compound, and then by extension, remember which substances it will react with, the products of the reaction, and the phenomena of the reaction (including thermal changes, light phenomena, gas odors, etc.). This is a long-term accumulation process, don't be in a hurry, do more multiple-choice questions and fill in the blanks, and do the correct solution process of the wrong questions, don't blindly memorize, but understand.

Difficulty is relative and may vary from person to person. But generally speaking, junior high school chemistry can be regarded as a relatively basic and simple stage compared to high school or college chemistry.

Junior high school chemistry mainly involves some basic chemical concepts and experimental operations, such as the properties of matter, elements and compounds, chemical reactions, etc. Compared with chemistry at the high school or university level, junior high school chemistry may be less difficult and focus on the mastery of basic knowledge and the operation of basic experiments.

However, learning chemistry still requires a certain way of thinking and memorization, and some auxiliary learning methods and practices may be required for the understanding and application of some abstract concepts. For some students, junior high school chemistry may also present certain challenges, requiring active study and practice.

The key is to maintain interest and curiosity, actively participate in practice and experiments, and communicate more with teachers and classmates.

It's not very difficult: chemistry is a liberal arts subject in science, and you need to secretly memorize the chemical reactions related to the fierce Xiang equation! I don't need to look back at the knowledge I have learned before, strengthen and consolidate, and the periodic table of the elements can be memorized on the basis of what the teacher has said.

Find out their patterns, and doing so will be like a fish swimming in water.

I'm good at chemistry, so I'll have some experience.

Generally speaking, it is enough to memorize the principle, and it is not required to memorize the old man, which is easy to limit the way of thinking.

A few suggestions.

1. Listen carefully in class, and the high level should reach the level that the teacher can immediately point out if he makes a mistake, and even more nb point that he can take the teacher to the ditch if he makes a mistake (sorry, I'm just like this The low level of Daxun just keeps up with the teacher.)

2. The basic principle must be mastered, and this must be memorized and memorized.

3. The method of solving the problem should be flexible, such as the conservation of elements, the conservation of electric charge, and the reaction of the column, so that the solution is basically not worried

4. The reaction equation should be memorized one by one, don't use a hammer in the east and a stick in the west, the effect is not good. As for trimming, if you want to learn well, you need to be able to analyze the products yourself and be proficient in completing the trim of the missing term.

5. It is best to find me knowledge across disciplines, such as the law of gravitation gm r 2 electric field force kq1q2 r 2, you can use this to analyze metallic and non-metallic properties, which you may not understand, but I often use it, and I will not miss the problem

6. I won't ask the teacher more, I will, and my classmates ask you to explain it to others (especially with the stupider ones to understand Duan Sheng) to experience what it feels like to be a teacher.

It's a great exercise in your abilities.

Personally, I think that if you don't want to memorize chemical equations, your chemistry score will definitely improve, and some necessary equations still need to be memorized at this time.

In fact, chemistry scores can also be improved, although delivery is very important, but it is also very important to study and brush questions, these behaviors can improve our chemistry scores.

It can be improved, because instead of memorizing all the chemical equations, then the chemistry score can be improved, and we should pay more attention to understanding them in a way of thinking.

In the exam, there are some content related to chemical equations, if you don't memorize it, it will cause you to choose this choice or fill in the blanks and there is no way to continue, resulting in you losing points.

The chemical equation is not memorized, but understood, and you have to try to understand the principle behind it, and also understand the four basic types of reactions: metathesis, displacement, compounding, and decomposition.
