How to learn chemistry and history quickly, will be in a hurry,

Chemistry is a science subject, and it is important to memorize formulas, and secondly, you should be familiar with books and practice more experimental problems. History should be read more, and it is best to review it after class. Good luck with your exams!

Chemistry should be read and memorized. History, on the other hand, needs to be read more, and you don't need to deliberately memorize it, and you will naturally remember it after reading it a few more times.

Find the teacher's past exam questions, mark the high-frequency test points, and then look at the textbook is easy to pass.

By talent. Sister, I didn't know how many tutors I hired for chemistry back then, and it was still very bad.

Physics eats apples in class all day, and it's still very strong.

What to do...

Study hard... It's a way...For solving general problems, it's generally those few routines to find good classics.

My method may be simpler than the previous big brothers, but I should be able to do these things.

Get interested in chemistry: It's fun to imagine chemistry. Very interesting. Very simple. Slowly you will have self-confidence. Remember: You can never learn the best subject without interest.

Because you lack a heart that is burning for it.

Take good notes: Generally speaking, teachers will talk about more important things in class. Will also write out. These must be mastered. And you have to use it freely. What's the point of not learning it if you can learn it but you can't use it.

Clever memorization: This depends on the individual's approach. Everyone's approach is different, but there is one thing: remember to remember, remember to be accurate. For example, me: remember the periodic table like 5 divided into a sentence.

It's as easy to remember as a poem.

Let's memorize numbers 1-36 first. If you master it, you can also look at it vertically.

Find your own mouth to dissolve the table: if the nitrate salt is missing in water, the potassium, sodium and ammonium salts are soluble.

You can make it up yourself.

Memorize the chemical formula of the stove. Speed dating chemistry equations.

You can ask your teacher about this. Because there's a lot of this method, and there's a lot of content. You don't necessarily understand it for a while. Take your time.

It's very important to roll the book, and the equation is the most basic of chemistry).

Keep in mind the process and the results.

This is the most favorite laboratory question in chemistry.

First of all. The name of the chemical should be understood and used.

Secondly, the process (i.e., the reaction phenomenon) should be known.

At last. The results need to be calculated. You have to understand this.

If you really want to do well in the exam, it is not enough to know more than textbooks, so it is a good way to read more extracurricular books...

Don't do too much about the question.

Personally, I think chemistry is done in a day.

10 choice questions (no type questions), 1 experiment (preferably synchronized with the textbook experiment. You can also do it outside of class), 1 calculation. That's enough.

Chemistry is nothing more than that. It's up to you to find the restEveryone's approach is different. Maybe you're looking for something better.

It is not difficult to learn high school chemistry well, you have to find the main clues that you need to learn chemistry, such as the chemical reaction equation and the periodic table. In fact, chemistry questions are the same as physics, they are all about equilibrium relations, to find equilibrium relations, you have to master some basic knowledge first, equilibrium relations are generally divided into conservation of matter, conservation of particles (molecules, atoms, electrons). The rest of you is to master the chemical equation test, my feeling is that as long as you find the equilibrium relationship, set the unknown quantity as an unknown number, and then list all the equilibrium as equations, and then form a system of equations, you can generally solve it, remember that almost all equilibrium comes from the chemical equation.

I will summarize some of the methods I learned in Li Xiaopeng's new blog, you can take a look: 1. Read what you just learned 3 times a day, about 10 minutes each time, which is the key small amount of multiple methods. 2. There should be a correction book, but when correcting mistakes, it is necessary to have some analytical ideas and methods, which will be of great help to future learning.

3. Learn new knowledge, pay attention to the connection with existing knowledge, such as learning the law of the gradual change of alkali metal chemical properties, combined with the metal activity sequence table, directly obtain K than Na live wave, get alkali metal more and more active wave, by Na can react with water, and Cu cannot, the more active the metal and water reaction is more intense (no reaction is considered to be 0). This is just one example, in fact, many things in chemistry do not need to be memorized by rote, and the rational use of existing knowledge for effective memorization saves time and is not easy to forget. If you don't think it's detailed enough, just go to the blog I said and take a closer look, in addition to the specific learning methods and problem-solving skills about chemistry, there are also learning methods and learning materials for other subjects, you can take a look, he used to be the first place in the college entrance examination area, my previous chemistry scores were very average, and then I learned from his methods, and now my chemistry scores in our class have been in the top three, so the method is right, the grades will definitely improve, I hope his method can also help you, come on!

In fact, it is not difficult to learn chemistry, that is, to memorize all the chemical symbols and formulas in your mind like you remember the names of celebrities, and think more about them when doing problems. Everything is the same.

Read more books, remember more, and don't even need a tutor!

In fact, it is to do more questions with more heart, not more questions. Comprehend in the process of doing the problem.

Methods of learning chemistry.

Due to the length of the article, I have to link to you. Forgiveness!

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.

No way, read more books and do more questions.

I am a chemistry teacher.

I think so. Chemistry is a lot of sales.

But it doesn't have to be rote memorization.

What you need is to understand it.

For example, a chemical formula.

CO2 (carbon dioxide), then you can think: what are the properties of carbon oxide, what kind of substance does it belong to, what methods can be used to collect it, what are the laboratory methods, what are the uses, etc. That way, you won't feel like a chemical formula gives you a purely carbon dioxide chemical formula

co2。Of course, the most important thing in studying chemistry is to learn the chemical properties of substances and the principles of chemical reactions. In short, it is necessary to learn the extension of a knowledge point.

Hope you can try it and then learn chemistry well.
