How to learn chemistry and how to learn chemistry well.

First of all, I wish the landlord progress in his studies and academic success.

I am the representative of the chemistry class, and my chemistry grades are always in the top three, so let me share my experience:

1. Interest is the best teacher, don't be afraid of difficult problems, change your thinking, challenge him, think about the joy after making the problem, you will be interested in him.

2 notes, chemical knowledge points are very miscellaneous, but the structural characteristics of substances can be divided into several categories, induction, there is a general grasp, and then the respective characteristics of each substance will be noted against the notes, and the commonality will be recorded, so that there is a systematic network, rather than a complicated and impossible way to start.

3. Review the past, review it often, and you will remember it a few times.

4 Faith, don't always think that this is your lame subject, pay attention to it, not give up.

Believe in you, you will succeed.

First of all, understand the content of the book, the properties of elemental compounds, reaction equations, and various things that need to be memorized in textbooks, and then do questions, do not seek more but refinement, the focus is not on how many questions you have practiced, but on how much knowledge you have mastered and remembered, and then whether you can use it proficiently. Chemistry is different from other science and engineering disciplines in that the memory is very wide and fragmentary, so you must prepare a notebook to record what you don't know or know. The knowledge mentioned here is not a large number of board books that the teacher talks about in class, the things on the board are in the textbook, so there is no need to record, what you want to record is the knowledge that you have not seen or do not understand when the teacher talks about the exercises, you should be concise and concise, listen and memorize, and then usually look at it more, and make them long your things.

Chemistry is first and foremost an interest, and you may have to have a good impression of your teacher first!

Chemistry is actually very simple, many of them are regular, but what you remember is that it is abnormal with the so-called laws, for example, the oxides of alkali metals are only lithium oxide and there is no lithium peroxide, but sodium has sodium peroxide! The oxide of potassium is more complex.

There is a lot of fragmentary knowledge of chemistry, and this can only be accumulated by the usual bits and pieces! Happy learning!

Chemistry is like a half-literate discipline, and only a certain accumulation can cause qualitative change.

1.Memorize the basics.

The basic knowledge of chemistry includes the periodic table, the properties of basic compounds, the reaction formulas of compounds, etc., which have to be written down by yourself, and all the chemical knowledge in the following years revolves around these basic knowledge. However, rote memorization is not recommended here, and it is difficult to retain the knowledge memorized by rote for a long time, and it will not be used to make use of it. I recommend memorizing it on the basis of knowing its essence and principles.

2.Chemistry is a discipline that develops based on several fixed principles.

All complex reactions are carried out by several fixed principles. For example, the vast majority of reactions in organic chemistry are essentially based on the forces between atomic clusters of organic compounds, and chemical reactions are carried out in a low-energy state.

3.Dividing the area is a difficult task.

Chemistry encompasses a wide range of branches, including inorganic chemistry, organic chemistry, physical chemistry and biochemistry. Small aspects include the basic results of the compound, the chemical reaction equilibrium, etc. It is important to distinguish which part is the weakness and which is the key point for yourself, and it is not difficult to learn chemistry efficiently.

4.Boost interest.

At the end of my freshman year of high school, I also chose chemistry, because I changed chemistry in the middle of the year, and I didn't listen to chemistry classes much before. I wasn't interested in chemistry at the time, so I didn't listen to much in class. At that time, I was going to choose physics and chemistry, but I suddenly didn't interest in biology when I chose a subject, so I changed biology to chemistry.

So I struggled with chemistry in high school. First, because I didn't have a good foundation in chemistry in my freshman year of high school, I didn't understand many simple things, so I couldn't keep up with the rhythm of the class, and then the class kept dragging on, and I didn't understand that more and more. I didn't take the second class seriously, because I really didn't have much interest in chemistry, and because I didn't have a good foundation, I couldn't understand the class, and the classes were basically all over the water.

Third, high school chemistry is getting harder and harder, especially in the third year of high school, when you can't keep up with it. Moreover, in the third year of high school, many subjects will increase the amount of homework, and it is difficult for you to spend more time making up for chemistry, and your other classes may fall because you don't spend time reviewing, which is a great loss. So I suggest that if you are poor in chemistry, you should make up the chemistry foundation before the third year of high school, at least you will memorize the basic content.

The basic content of chemistry is actually to ask you to memorize more, memorize more, and brush up on more questions. Then the knowledge in the textbook is really important, read the textbook more!! If you didn't study hard before, the result would be that your foundation was not very good, and then your score was not high.

Because the college entrance examination is approaching, my recommendation is to improve my score as much as possible. That is, to make up the foundation, and following the teacher's rhythm is very important for students with average or even unsatisfactory grades. If the teacher can't understand and keep up with the class, then the foundation is not good, then you can preview the content of the teacher's lecture in advance before the teacher's class, and you should review it in time after class.

Students with average grades at this time are not focused on difficult problems, the last few questions. Rather, it is a simpler, easier topic ahead. So don't think about me going to the problem to add points or anything when brushing the questions.

That's all impossible. Then brushing the questions is really important, because the question type is roughly the same, that is, the method may change a little or you need to combine other knowledge points, so you should lay a good foundation before brushing the questions, and don't blindly go in and brush the questions. After understanding all the basic content and knowledge points, go to brush the questions.

Another very important is the method of problem solving, when the teacher explains the question type, one point should follow the teacher, the teacher will generally talk about the method of this type of question, plan with the answer, list the answer steps, and then suggest to do the question again and sort it out. In the end, it is necessary to grasp the foundation, the foundation is very important, and it is also very important to consolidate the questions!!

Chemistry is a liberal scienceIt's all about memorization, such as chemical equations, all valence states of a certain element, the distribution of some important main group elements in the periodic table, the physical and chemical properties of some substances, the special properties of some functional groups of organic matter, etc., if you want to learn these well, you must first memorize more, summarize more, do more questions, and practice is very important.

The mastery of chemical equations in high school is not to memorize as much as possible, but to classify them, to support the reaction principles of each class, from the surface to the inside, from the shallow to the deep, from the individual to the general, I here classify them as follows:

(1) Inorganic aspects

1) Four basic reactions: compounding, decomposition, displacement, and metathesis.

2) Oxidation-reduction reactions: intermolecular redidation-reduction, intramolecular redidation-reduction, disproportionation reactions, final reactions, for example, zinc and dilute hydrochloric acid reactions, heating potassium chlorate to produce oxygen, chlorine gas in calcium hydroxide solution to make bleaching powder, hydrogen sulfide and sulfur dioxide reactions (according to the above classification corresponds to an example).

3) Ionic reaction: the reaction between ions, all metathesis reactions between acids, alkalis and salts, must obey the conditions for metadecomposition to the end. reactions between ions and molecules; For example, the reaction between chlorine and iodine ions, and the reaction between sulfide and acids, bases, and salts.

Reactions between ions and electrons, such as hydroxide ions losing electrons at the anode. Electrolysis reactions in aqueous solutions, such as the electrolysis of sodium chloride aqueous solution to produce hydrogen and chlorine. Fitting reaction in aqueous solution.

4) Hydrolysis of salts: hydrolysis of strong acid and weak alkali salts, hydrolysis of strong alkali and weak salts, hydrolysis of weak acids and weak alkali salts, double hydrolysis reaction, etc.

5) Reversible reactions, and reversible equilibrium movements.

6) Exothermic reaction and endothermic reaction.

(2) Organic reactions have

1) Replacement, addition, organic redox, intramolecular dehydration, intermolecular dehydration, polymerization (polyaddition, polycondensation), halogenation, sulfonation, nitrification, cracking, cracking, elimination, decompletion, hydrolysis, esterification, color development, high-temperature dry distillation, hydration, etc. It is necessary to grasp the principle of each reaction, the characteristics of each substance, the conditions of each reaction, and the various reactions to each other, and study the inevitable laws between them.

The most important thing is to learn the basic principles well.

And then it's all over the place.

Don't go for rote memorization.

1.Let go of the psychological baggage, don't think that you didn't study well before and arbitrarily think that you can't learn high school chemistry, in fact, junior high school chemistry has little impact on high school, you must believe in yourself, and you must stand firm psychologically.

2.Do a good job of pre-studying, everything is pre-established, draw with a pen if you can't see something in the book, and wait until the class to watch the teacher explain.

3.After class, you should review the basic knowledge section of the textbook and take your own notes, including a book of your own correction (use different colored pens as much as possible).

4 Doing questions This is very important, do more questions, but don't just indulge in doing questions, you must understand what the key points of these questions are in the questions Remember: from being able to do some questions to being able to meet a class of questions Because many questions are ever-changing, it is necessary to also write down the type of question that you think is very important, which is the question type, not just the question 5 Classification If you don't understand, you must ask the teacher, whether it is the chemistry teacher, don't think that these questions are simple and embarrassed to ask, which will exhaust you, You have to believe in yourself and the teacher, and you have to think independently after the questions, don't think that you really understand, you must think, and separate some questions from different test points, so that you can be kind and have clear ideas 6 Reflection Reflect on why you did wrong and why you can't do it, and still exchange chemistry learning experiences with other students Keep summarizing your own set in reflection 7 Believe in yourself

Okay, you must be able to do it The above is my previous experience in studying chemistry, I hope it will have some effect on you, and finally I wish you a smooth exam, like a bamboo, straight to the examination room, and shine

Reflect and look for what went wrong.

There are not so many things, summarize the equations in the book well, and then do more problems (these two orders cannot be reversed), so that you can deepen the impression and find omissions, persist for a month, and the results will come up, and your interest in chemistry will also come up, thus forming a virtuous circle. I would also like to add that when memorizing and understanding equations, you can think of each group as a building block, or something you like.

Read the textbook repeatedly, think about it while reading, and then do the questions.
