How do you learn chemistry? I m a junior in high school, but I haven t studied chemistry much since

The quickest and most effective way to do this: Take advantage of the holidays and start memorizing equations to figure out how chemistry works. Principles are extremely important in the study of chemistry.

There are also experiments, take the experiments in the textbook and look at them! Chemistry is a liberal arts subject in science, and memorization will be fruitful if you put in enough effort to memorize it. Hopefully it's not too late!

It's better to find a tutor, or a college student studying chemistry, and that's a good idea.

Never mind.. Just watch and think more.

For the chemical equation - memorization, it is best to understand the memorization, including the memory of redox differences are helpful in the memorization of chemical equations.

For the principle of chemical reactions, understanding, in essence, understanding is the most important, do not half-understand.

For the experimental questions - do more, the expression of the experimental questions,

You can start learning from now on, you definitely don't understand it at the beginning, you can learn while listening, and you can be exposed to the content of the first to third year of high school in the whole review process of the third year of high school, you should listen to the new class, master some fixed problem-solving skills of basic knowledge, and you can get 40 points and also lay a good foundation for your tutoring next year Chemistry teacher Liu.

Interest is the best teacher, and then it is recommended that you listen carefully in class, practice more, summarize mistakes, and remember rules, even if it is the most vulgar method.

There are two main lines of high school chemistry.

1) Periodic table of chemical elements.

2) Reaction principle.

It's good to grasp these two main lines.

Do the questions one by one, first pick the easiest you can do, cultivate some confidence and interest in yourself, and then let the teacher tell you about the amount of periodic law of the elements, the properties of various groups of elemental substances, experiments, including organic, these are flesh and bones. Learn or memorize to do the questions, and you have to memorize a few of the same question types.

Remember to remember, don't just ask the teacher.

To put it bluntly, you must practice more and think more, you must fully understand why it is answered this way for a question, your thinking must be clear, and you must keep in mind what formulas you need to use. Don't just do the questions for the sake of doing the questions, no matter how many questions you do, it will be meaningless if the same type of questions change slightly, and you must be able to draw inferences.

The sophomore year of high school is still in time. The main method is still to do the questions.

Choose a chemistry tutoring exercise book recommended by teachers and classmates, with key points and example questions before each chapter, and do the questions after reading it. The key is to do the questions, you have to understand what knowledge points you want to test for each question, test the memory of the relevant knowledge points together through the logical relationship to remember, do not understand or do wrong to ask the teacher and classmates, ask until you understand thoroughly (don't be embarrassed if you don't understand at first, ask another person again, many times you can't understand and learn badly because the person who teaches has a problem); Therefore, the analysis time may be longer than the time to do the question. Do 2 sets a week, and over time, you will gradually find that many questions are very similar.

By the time you get used to the feeling of bypassing and drawing inferences, congratulations, you've mastered the key to high school chemistry!

Finally, I would like to mention that although chemistry in high school is still very narrow, when you get to university, you will learn more theories and experiments, which will make you feel enlightened and happy to create new substances! I wish you success!

In this way, you have fallen too much, and there are some things that must be remembered in every course, and the elements commonly used in the periodic table must be remembered, from which you can calculate whether each ion or (OH) is positive or negative, positive or negative, because the molecule is neutral, so the positive 2-valence ion can only be combined with the -2-valence ion. The more important ones are the law of conservation of mass, there are not many types of chemical reactions, neutralization, displacement, etc., the best way is to ask more classmates and teachers, summarize the ideas for solving the problem, I believe it can be made up. Good luck.

I now teach the second year of high school, chemistry, there are many things to remember, not very difficult, from your problem, you may be a girl, start from the basics, learn the law, learn the law, learn the law, and slowly understand it yourself.

Combined with life and reality, the learning effect is better.

The time is a year, neither long nor short, if you study hard, it will be no problem to make up for it. This is the method I gave you, and it is also the method I used, and I basically got a perfect score in chemistry in the college entrance examination. Of course, my foundation is better than yours, but that doesn't matter.

1. Junior high school has passed, don't live in this shadow and feel like you don't know anything. Just because it won't, it is more necessary to have a good start again. Then I suggest you do this:

The textbooks (two) of the first year of high school should be read carefully in a month's time, and they must be carefully read. You don't have to memorize everything, you just need to know what you know. After that, I reviewed it every week, and I was doing it on the weekend.

Especially the book in the first year of high school, which is the foundation of inorganic chemistry in the whole high school, and these review days are the process of your memory. At that time, I reviewed it at least 100 times, and I basically knew which page the knowledge points were. So can you learn to look good at your perseverance?

2. The first step is to lay a foundation for you, those knowledge will be understood, it will be used to answer questions, from which to supplement the knowledge points that are not in the book, the chemistry teacher will add a lot in class, and there will be questions in the questions. That's a process by which you improve. Don't pursue the amount of quantity, but do something targeted and inductive, so as to get something.

Finally, I hope you will learn and improve, and I am willing to share my experience if you have other questions.

It's not an optimistic question, but it's good that you're aware of the seriousness of the matter by now. This requires you to spend a lot of time every day reading books and buying some basic reference books at the bookstore. When you encounter problems, communicate with your teachers and classmates and ask for their help.

Although reading is not the only way out, there are many things that can be understood through learning. Change your outlook on life, your values, and your worldview. It will be of great help to your future life journey, I hope you don't give up! Come on.

I haven't learned, I haven't learned well, I haven't learned well, but if I learn, it's much easier to do, you can read the text by yourself first, first understand the content of the text, and then buy some materials to see, buy some questions to see, the key is to make up your mind. If it really doesn't work, let's find a teacher.

If you are interested in chemistry, it is easy to do, read more books when you have nothing to do, deduce chemical equations, start with simple ones, find your feelings, and in addition, group study is a more efficient method. You can form a study group with your classmates or friends to monitor each other and ask each other questions.

Learning from the West relies on diligence, as long as you work hard

1. Understand the various reactions.

Chemical reactions include reduction reactions, oxidation reactions, chemical reactions, decomposition reactions, acid-base neutralization reactions, etc. In chemical reactions, we must firmly grasp the change of valency, and knowing this, I believe that it is not difficult to react.

2. Do as many experiments as possible.

Practice is the only criterion for testing truth, so experiments also account for a considerable weight. You need to understand the use of some experimental equipment, such as: condenser tubes, test tubes, iron frames, alcohol, etc. In addition, when doing experiments, you must pay attention to your own safety.

3. Preview before class.

In class, the teacher will often talk about the difficult and easy to mix points, so before the teacher talks, you must be prepared for the preview.

4. Connect with life.

The knowledge points learned are mostly related to real life. For example, iron rusts because iron undergoes a slow oxidation reaction in the air.

Like you, I didn't know anything about chemistry in my junior year of high school, but I also learned chemistry well in my third year of high school, and then I was admitted to the chemistry normal major of the university newspaper, and now I should be in my senior year. First of all, you need to have the confidence to learn chemistry well, because compared to mathematics and physics, chemistry is the easiest.

1.Chemistry belongs to the combination of arts and sciences, both requires memory and understanding, you have to calm down and read the book chapter by chapter, the book is the foundation, it is the "sect" that does not deviate from its sect, you don't want to see others keep doing the question, you blindly follow it, the more you do it, the more confidence you have, the more you don't. Therefore, you must at least do the knowledge and questions in the book before you can do the exercises.

2.I know that if the teacher leaves the paper, he will say that if you don't do it, the teacher may be criticized for checking the homework, so you should go to the teacher after class and let the teacher find a way for you, maybe the teacher will give you the privilege to hand in the homework after reading the book. Don't alienate the teacher, every teacher will not refuse a motivated student.

3.It's a holiday, I hope you can grasp yourself, be more conscious, stay away from the TV and computer, and devote yourself to studying, I think a vacation is enough to read the high school chemistry book again, pay attention to the first book to read, if you don't know at all, it's best to get the junior high school book back and take a good look.

We must remember that "everything changes are inseparable", and you can't blindly do the questions, and the confidence in doing the questions will be higher and higher if you understand the book.

If you want to study well, you must grasp this summer vacation, because the college entrance examination is not a joke, and repeating it is very painful.

High school chemistry is actually not difficult to learn, mainly because the memory stuff is more miscellaneous. The key to learning chemistry well is to clarify the knowledge points learned and express them in the paper. For this, you can first list your weaker links and then focus on reading books and doing questions for these places to break through, but you must understand, don't ask the teacher, the teacher will not be annoying.

Also, because of the miscellaneous knowledge points, you have to make certain notes when you read books and do questions (I mean all the chemistry questions you did in your third year of high school, including your own, the teacher's, and the monthly exam, but you have to do what you can, just the right amount, because other classes also take time), mainly because you have to work hard to understand, these notes are best read once a week, you think, there are more than 40 weeks to take the college entrance examination, can you not understand what you don't know more than 40 times?

Mine, you can add me, tell you specifically.

Actually, it's not that hard. Just understand the book and do a few questions in high school.

Do more questions, such as mock questions, real questions, etc.

Chemistry is a liberal arts in science, and it is enough to accumulate more knowledge points, so take all the knowledge points over the same time, and then do the corresponding questions to consolidate it.

In fact, I don't advocate complete self-study, because reviewing by yourself will leave out knowledge points. Moreover, the situation of mastering the knowledge points cannot be fed back in time, resulting in a very poor review effect. However, it is recommended that you can systematically complete the knowledge points that you have missed or will not know while keeping up with the teacher's review.

Here's what I learned during my junior year of high school.

Clause. First, it is necessary to grasp the basic points of the teacher's lectures in class and take notes frequently.

Clause. 2. Return to teaching materials. During the third year of high school, many questions came from the textbooks, including experimental questions and concept questions, which were derived from the textbooks and changed.

Clause. 3. Pay attention to the analysis of exercises. Don't just focus on doing the questions, but sort out the knowledge points in each question. If you don't know how to ask a question, look at the textbook or notes.

Fourth. Error set. Don't underestimate the wrong questions, this is quite important in the review process of the third year of high school.

Entering the third year of high school, the time for revision will increase. The teacher is always frying cold rice in class. Find the knowledge points you don't understand from the wrong questions in time, and ask the teacher and classmates.

Just plug in the loopholes.

The last point is to persevere. The effect of revision will not be obvious at first. But it is necessary to believe that quantitative change will cause qualitative change. Only by persevering can you definitely improve your chemistry scores.

I wish you a qualitative leap in your chemistry grades.

Personally, chemistry can be taught by itself, and my chemistry can be said to be self-taught.

A person's opinion: the prime minister is to read every experiment in the book, the chemical equation to work (to understand the reaction process of each equation, remember what chemical phenomena will appear in their reaction), ion reaction to know which reactions are not reactable, precipitation, this is to rote memorization, but you can find a way to memorize that you think is suitable for you. This aspect of the periodic table is also very important, to be proficient in memorizing the first forty elements and to know the corresponding positions, and then to memorize all the elements of the seven main groups, to know the relationship between the elements of the same main group, and so on.

A good understanding of the periodic table can help you understand and expand the properties of many elements, so that you don't have to memorize so many things that you can deduce. The most important aspects of inorganic chemistry are the periodic table and its properties, as well as the ionic chemistry.

In terms of organic chemistry, in fact, those chemical reactions (including reaction phenomena) are memorized, and it is almost the same as organic chemistry.

Of course, it must be necessary to do the questions before you finish reading a small section, and you have to do some of the questions in this section to consolidate, and you can do more reasoning questions when you feel that your foundation is good, it is a topic to improve your ability. The test is relatively wide, and you must have a certain foundation to make it.

First of all you should read the book! Memorize the basics of the book, such as the phenomena of chemical reactions. Secondly, you should do more questions! Doing questions can help you familiarize yourself with what you have learned and apply it in practice. Finally, learn from others.
