It s the second semester of high school, and the previous chemistry was confused, and now how to lea

In high school chemistry, inorganic is the absolute focus.

Memorize all the formulas of everyday reactions, phenomena. Recite the first 20 of the periodic table (by necessity) and remember the columns.

But high school chemistry is also inevitably exam-taking, do more questions. Fortunately, you are now in your second year of high school, and you can definitely make up for it with a summer vacation.

To put it bluntly, chemistry is the proficiency in the use of formulas and the mastery of the chemical properties of individual substances!

Don't worry. First of all, you have to have information, don't be afraid of anything, there are not many knowledge points in high school, especially the college entrance examination, which are all basic questions, don't drill the horns when doing the questions, in addition, you must analyze the questions carefully and read more books.

Whenever you feel that you don't have a good grasp of a certain knowledge point, you can turn to the book and read it.

Don't think you'll just read a book once.

In addition, it is necessary to prepare a notebook and take notes, very long, double it often, do not have to memorize anything, the main thing is to be attentive, it is really not difficult to chemistry, and the logic is strong!

It's all very coherent and very regular.

Elements of the same family and cycle are similar!

Just remember the differences.

Let's learn together!

I wish you progress. Happy.

Don't worry, there is still a review for the third year of high school, and now you have to preview the new class first to keep up with the third. In the past, just memorize the periodic table, and those rules have to be understood one by one. In organic chemistry, you have to read books and questions, how they are composed, how they are formed, how they are reacting, and then they are inferred.

After that, just read the book next to each other. Let's focus on the details.

You'd better be able to combine the metals you learned in your first year of high school. Topics such as non-metals should be well consolidated, and some topics related to the quantity of substances should be appropriately done to achieve a deep understanding. And then use this knowledge to reinforce.

Deepen the chemical balance. Ionization equilibrium. Comprehensive application of hydrolytic equilibrium knowledge, so that it should be fine.

It is recommended that you buy a set of gantry topics, try to see and do it, and when you are done, you will basically keep up.

It shouldn't matter much, chemistry books are divided into chapters, and the knowledge points in a book are closely related, and there is not much correlation between books. Now take the class seriously, understand the knowledge points, and try to understand the previous ones when the books are interspersed with the previous content (you can read the previous books by yourself, ask your classmates or teachers), don't rush, take your time, the important thing is not to understand and understand what you are learning now as before. Then use your spare time to take a look at your previous knowledge, believe in yourself, and as long as you persevere, you will definitely improve.

I'm only a freshman in high school, but our school has already taught organically, and I have a deep understanding that a subject seems to be divided into two, and I should do more questions, or discuss it with the strongmen in the class.

1. Pay attention to textbook knowledge and ask more questions

Disdain textbooks, say that the content of textbooks is simple, like to buy reference books, and even follow the trend to buy competition books, college textbooks, in fact, these things are simply useless for you now, we refer to books, there are many knowledge points in the textbooks that have not been understood, and the problems that need to be thought about have not been solved.

2. Pay attention to the basic principles and laws of chemistry

Chemistry is a natural subject, it has certain rules, such as the most headache for high school students - chemical balance, balance influencing factors, as well as water ionization balance, salt hydrolysis balance and calculation, etc., several combined, many students are discouraged, so we must understand its principle and essence in learning, only in this way, can we learn it well.

3. Pay attention to summarization

High school teachers will not be like junior high school teachers, who will talk about everything in detail, so when they reach high school, everyone should learn to prepare, learn to make summaries, and cultivate independent chemical awareness.

4. Consolidate classroom results

Before each class, don't be in a hurry to loosen your mind all at once, but take a few minutes to quietly think about the basic content of the class to achieve a consolidated effect.

To learn high school chemistry, you must not feel that it is difficult and lose confidence, as long as you find the right method, then learning chemistry well is also a very simple thing.

I feel that the sea of questions is not necessarily good, the important thing is to summarize, it should be good to summarize yourself from now on, it may be difficult to come up, a waste of time but it is definitely worth it, for example, there are several kinds of short-cycle gas elements, what is the reaction of their nature and color, in fact, there are six kinds, but usually no one pays attention, and it is a waste of time when doing the question, (oxygen, ozone, nitrogen, hydrogen, chlorine, fluorine), colorless and odorless on three (hydrogen, oxygen, nitrogen), And their nature is completely incomprehensible.

I won't go into detail here, I feel that the knowledge is too fragmented to learn in the third volume of physics, I studied the textbook of 02, I remember that I summarized a sentence at that time: nine people, ten major discoveries, four nuclear reaction equations. It's easy to grasp the knowledge system of a book, the summary varies from person to person, so that it is not overnight, it is related to the usual learning habits, the knowledge of chemistry is relatively fragmented, I suggest that you write down the equations in the book, and it is best to memorize them with coefficients.

If you have anything else you want to ask, you can add me as a friend, I have been a tutor, and I am in my senior year, so I still know a lot about your high school situation.

If you want to learn a subject well, you have to master the skills of this subject, and no matter how many questions you do in chemistry, you don't know how to test your knowledge points, and you won't be able to do it next time. If you don't study well in your freshman year, your foundation will be relatively poor, think about why you didn't study well.

This means that your foundation is not good, you should at least take notes well in class, and you have to write down the content on the notes in your mind, and then according to the key content of each chapter, do the corresponding exercises to be proficient in the content you remember, don't be ambitious, step by step, the foundation must not fall behind, you can't feel good is good; In the past, the teacher did the exercises in class or by yourself, you must take them out regularly, especially if you make mistakes, you must pay attention, and try not to make the same mistakes the next time. There is no need to do so many questions, that will only make your brain more messy, as long as you understand some basic things, be proficient, and will apply, because the exam is not a remote thing, it is usually very common, the foundation is very important, and then adjust your mentality, you still have time now, you must not be in a hurry, take your time, be down-to-earth, when you study, you want to be efficient, not vain, come on You are the best

I am also a freshman in high school, and I recommend that you read more workbooks for chemistry, because there are many knowledge books in the workbooks that are not mentioned, and the teachers who produce the papers mainly refer to the workbooks. Remember, once you don't understand, you must ask, don't make excuses for yourself, don't feel embarrassed or anything like that, you must ask more, write more, remember more, and believe that you will be able to learn chemistry well. Because it's my own experience, it's very effective!

If you think it's good, take it!

Email me and I will have time to send you information

Do more questions and read the contents of the book a few more times, practice makes perfect.

Do more experiments and get interested in them!! Use your brain more and master the learning method. Encourage yourself, I'm actually smart!! Think more about others, they are not necessarily better than me!! Chemistry is not difficult in the second year of high school, I wish you success!!

Look at the textbook! Absorb the example questions completely! Re-sync do a lot of practice questions! over!
