Chemistry learning is actually a bit of a liberal arts, with a lot of content and fragments, and memorization is necessary.
It's a good idea to take notes and flip through them often. Summarize the methods in the process of doing the questions.
Of course, chemistry is a science subject, so you still have to do some calculations, analysis, and logical reasoning.
There are also four major balancing systems that are important:
Chemical equilibrium, ionization equilibrium, hydrolytic equilibrium, dissolution equilibrium.
-
The chemistry is just very piecemeal.
You still have to remember.
The teacher will also talk about some rules or something, remember them, and then apply them.
You have to analyze it yourself.
Sometimes you have to summarize more skills or something.

It may be a different place, I don't know what 3+1 means, but I'm in my third year of high school now, and I study chemistry by taking notes... Take a general review of the college entrance examination (similar to backgammon), look at it slowly from the beginning, and copy your weak and important foundation and attention problems in your notebook Look at it before the exam after copying it to ensure that you learn well Although the method is very dead, it works very well. The chemistry we are learning now is very dead, and the basic test is all basic, and the foundation is done, and there is basically no big problem.
-
Follow the teacher in class.
Find some practice questions to do after class.
The main thing is interest, and if you are interested, it will be easy to do.
If you have to stuff it, there will always be a day when you can't plug it.
-
You have a notebook ready.
There is also a mistake book.
It's indispensable, and when the exam is over, hold them and watch it.
-
Lay. Speaking of experience, believe me, the foundation must be laid.

In fact, I have a classmate who almost didn't study in the first and second years of high school, and passing is a luxury for him. In his third year of high school, he found a unique study method, and his chemistry scores in the third year of high school were all in the top five in his class. Here's how he learned:
1.Every time he wrote chemistry homework first, it became a habit later, and it was forced out at the beginning, and it was fine after that. 2.
He had a notebook and wrote down everything he really didn't understand. It may start more, then it will become less and less3He was really serious in class, and he always chased the teacher to ask questions after class.
First, learn the most basic knowledge, such as particle structure, periodic law, chemical formulas of various substances, chemical equations, various basic experiments, calculations, etc. Then according to your actual knowledge of chemistry to learn in a targeted manner, you can use some reference books or the Internet** to assist learning. Chemistry has a lot to memorize, and it takes some hard work.
It should also be noted that chemistry and practical life are closely related, and in order to learn chemistry well, we must pay more attention to various chemical phenomena in life and do more chemical experiments.
Do more questions, read more books, and memorize more. The chemistry knowledge points in high school are very scattered, and you need to summarize and memorize them by yourself, and you can also buy a resource book to read the knowledge points. Pay attention to important experiments, in fact, you can remember a lot of things by doing more questions, just like equations, write more and memorize.

Listen carefully to the lectures, take more notes, read more textbooks, ask more questions, and correct more mistakes.

Chemistry is a fascinating subject. However, due to the characteristics of high school chemistry as "complicated, difficult, and chaotic", many students find it difficult to learn high school chemistry. So how can you learn chemistry in high school?
1. Listen carefully and take good notes.
Good notes are the condensation, supplementation and deepening of textbook knowledge, and the presentation and refinement of the thinking process.
Since the knowledge points of chemistry are numerous, fragmented and scattered, in addition to listening carefully and thinking positively, in addition to listening carefully and thinking positively, we should also write down the key and difficult knowledge of the teacher in our own words on the basis of understanding, so as to facilitate future review.
2. Review in a timely manner.
Revision is not just a simple review of knowledge, but considering the interconnection of old and new knowledge in one's own brain, and reorganizing it to form a new body of knowledge. Therefore, after class, it is necessary to review the content of the lecture in a timely manner, and do a good job of sorting out and summarizing the knowledge, so as to make the knowledge integrate and avoid the phenomenon of more and more chaos in learning. For example, if you learn about the bleaching properties of SO2 and chlorine water, you can compare them to find out the differences.
3. Learn to memorize.
Since there are many chemical knowledge points to memorize, it is difficult to memorize them if you rely on rote memorization, so you should learn to memorize them skillfully. The commonly used memorization methods in chemistry are: comparative method (often used for knowledge that is easily confused and interferes with each other.
The four similar concepts of isotope, allotrope, homologue, and isomer can be deepened and remembered through comparison. ), induction, song recipe memory, comprehension memory, and experimental memory.
Fourth, practice diligently. Practice is an important way to understand, digest, and consolidate classroom knowledge. However, the practice should be targeted, not a sea of tactics, and should be aimed at mastering the basic methods and the rules of problem solving. In the process of problem solving, it is necessary to pay attention to multiple solutions and inductive summarization of one problem, so as to achieve the effect of doing one problem and one category.
For example, the techniques commonly used in chemical calculation include: conservation method, relational method, extreme value method, average value method, estimation method, difference method, etc.
5. Prepare a "mistake book".
The purpose of the questions is to develop abilities and find effective ways to find your weaknesses and deficiencies. Therefore, mistakes should be corrected and recorded. When recording, you should analyze the reasons for the error and the correct solution idea in detail, and do not simply write an answer.
At the same time, it is important to go through the review frequently so that you can avoid similar mistakes in the future.
6. Pay attention to chemical experiments.
Chemistry experiments can not only cultivate students' observation, thinking, hands-on and other abilities, but also deepen their knowledge and understanding of related knowledge, so we must pay attention to chemical experiments. When doing experiments, we should ask a few more whys, think about how to do it, why we do it, and what else can be done, so as to achieve the purpose of "knowing what it is and why it is true".
In addition, in order to study chemistry well, we should pay more attention to social hot issues and life problems related to chemistry, and be good at combining book knowledge with practice.
In short, as long as the learning method is correct, I believe that students will easily learn chemistry well.

Chemistry? It's just to memorize the equations, learn to balance, and memorize all the experiments that should be listened to.
The equation in your book must be like this: 2h2(g) +o2(g) = 2h2o(l), right? >>>More
HA may be weakly acidic, weakly ionized, pH greater than or equal to 7
There are two main factors that affect the radius: one is the number of electrons outside the nucleus (generally speaking, the more electrons there are, the farther away from the nucleus, the larger the radius). >>>More
In this reaction, there is only the electron gain and loss of nitrogen element, the valency has risen and decreased, so C is wrong, the increase of nitrogen in metadimethylhydrazine is oxidized, it is a reducing agent, so a is wrong, the reaction is the recombination of atoms, so there is an endothermic and exothermic process, C is wrong, D is left, of course, there are eight electrons transferred from two N2O4 to N2 D is correct.
It doesn't seem to be a contradiction. The structure of the electron layer is the same, which means that it is the same three-layer and the same four-layer ......For example, Na and Cl, the radius of Cl is much smaller. >>>More
