How to learn chemistry! Ask for a self learning method in chemistry!

To learn chemistry, you should first take out the entire high school chemistry book for analysis, and the chemistry content in high school can be roughly divided into three aspects: organic, inorganic, and structural. You can analyze it through your own test paper to see if that part of the knowledge is not good, and I can try to help you.

A chemistry teacher.

What are you afraid of, chemistry is best learned, do the questions first, see if you can't do it or do it wrong, just look at the corresponding part of the content, information, and questions, until you do it well, and memorize it more in the process.

As long as you learn, it's OK, I'll show up to say, I counted down to chemistry in the second semester of my sophomore year, I didn't bring textbooks to class, and the teacher started to learn after staring at me, and then I was basically able to achieve a full score, chemistry is actually relatively simple, the key is to work hard, come on, I hope you can be admitted to a good school.

Find a way to connect chemistry with some of the things in life to make yourself interested in learning"If you are close to your teacher, you will believe in it"Maintain a relationship with the teacher and get to know him (her) well, I have tried to use it well, and the effect is relatively good.

Rote memorization is not good for him to see.

I came from a chemistry background, and I majored in chemistry in college

Chemistry learning is done in several steps:

1.In fact, chemistry is a subject of both arts and sciences, so it has certain concepts, definitions, and the memory of some chemical symbols and rules, which are the foundation of the foundation, so I think this is the first step, that is, to be very familiar with some knowledge points in high school chemistry, and the first step must be to do a good job of literacy and completely clear some knowledge points. For example, what is an electrolyte, what is a redox reaction, what is an organic matter, and so on.

Of course, you can't just memorize them by rote, you have to digest them in your own way on the basis of understanding.

2.Thousands of high-rise buildings rise from the ground! Therefore, on the basis of the first step, it is necessary to find some ways to solve the problem, which requires a certain amount of practice.

Therefore, the second step is to carry out a certain amount of thematic exercises on the basis of a large framework, one module at a time to clear the blind spots of knowledge, know how each knowledge point will be tested, and what is usually tested.

3.After doing a certain amount of practice, the most important thing is to summarize it well, only what has been summarized is your own, so that you can get twice the result with half the effort! The topic is not to do a lot, but to practice in a targeted manner, and then immediately correct and summarize, so that you can get results.

On the whole, it is a three-step process, 1Removing the blind spots of textbook knowledge and achieving a clear understanding of the context of knowledge points is the top priority! The foundation of the basics!

2.It is divided into thematic modules and practiced in a thematic manner.

3.After doing the exercises, immediately revise and summarize, and be sure to score points for some basic questions, and you can choose to give up if it is too difficult.

4.In the second half of the sprint stage, you should do the mock paper within the specified time, so that you must not only know how to study but also know how to take the exam, and know yourself and your opponent. That's how you can get a high score--- in terms of exam-oriented education!

Literacy + Thematic Exercises + Summarizing from Time to Time + Mock Papers.

In fact, the most important thing in chemistry is to understand, understand the characteristics of substances and deduce the properties of similar substances, such as memorizing equations, just remember the special one, then the same reaction of similar substances can be remembered, and there is the experiment, to pay attention to the experiments in the book, you must understand, the sequence of each step of the experiment, the reason for this, you can do more comprehensive experimental problems. You can do the questions first, and then understand your weaknesses through the results of the questions, and focus on reviewing this part and doing some practice questions, so that you can check and fill in the gaps, which should be very effective.

Read more books, be patient, read more times, read more, memorize more, and then do the questions to deepen your memory.

1. Write chemical equations (senior 1 to 3);

2. Review key chemical experiments; Analyze the purpose of the experiment;

3. Summarize the properties of each element according to the order of element-oxide-acid-base-salt;

4. Do more questions: five-year college entrance examination and three-year simulation;

5. If you have the spare time to learn, you can preview "Principles of General Chemistry";

Let's choose the best

I still haven't found the basic principles and methods of chemistry, so let's figure out the principles first, many of which can be inferred from one another, and you need to communicate with the chemistry teacher.

Chemical formulas should be memorized, and special circumstances should be clear.

The knowledge points are scattered, and you should memorize more and memorize more.

Chemistry: Mainly to memorize some properties, write equations, etc. Textual things, you can take a look at it and memorize it.

The key to theoretical things is to understand, and if you understand it, you will be able to draw inferences from one another. For example, in a chemical equation, in order to write a correct chemical equation, you must first write the chemical formula of each reactant and product, and in order to write the correct chemical formula, you must understand the valency. If you just rely on rote memorization, it is still easy to forget when it comes to the exam, and understanding is the most important thing.

So you have to memorize more practice questions, such as multiple-choice questions, the teacher gives you some special properties to choose, so more practice can invisibly help you remember. The effect of light memory is not good. The more you practice the nature of those special substances, the more you will remember.

The big topic is reasoning, writing equations, and with a good foundation, you will not be afraid.

In short, it is a process of accumulation, the more you know, the better you learn, so memorize more and choose your own method.

Good luck with your studies!

Chemistry is actually very interesting, you have to be familiar with the periodic table, be familiar with the chemical formulas of common substances, understand how chemical reactions occur, find out the rules, and slowly you will fall in love with chemistry.

Formulas can't be memorized, summarize a set of self-discovered reactive patterns, summarize the similarities, and unify the memory. That seems to be a little better. It's still important to accumulate.

Since high school, I didn't like to study chemistry, but now I can't help but push myself, but how to learn it myself, our whole school students use this method to learn physics and chemistry. The following is from the best preview of Yangcheng Evening News.

First of all, you have to follow the teacher when you are in class!! Especially when he is doing chemistry experiments, you must pay attention. It also depends on the teaching experience of your chemistry teacher??? See if he can transport you into a world full of magic

You first need to start with chemical equations and some basic concepts of chemistry!! Don't be afraid that if it's difficult to learn, you won't work hard, and you have to do more chemistry problems

That's how I learned, and it's up to you!!

Learning methods: Concentration and good study habits are the most basic ways to save study time and improve learning efficiency.

1.The habit of pre-studying. Preview can enable you to connect with previous knowledge, discover new problems, think about how to solve them, and bring problems that you can't understand to the class to better listen to the teacher's explanation.

2.The habit of taking notes and organizing them afterwards. As the content of the course grows and complexes, taking notes helps to get to the point.

If the things you memorize in class are scattered due to time constraints, then you should organize them after class to make them comprehensive and organized. The process of sorting out is a very effective process, and it can also exercise your ability to analyze and summarize, so you should develop the habit of organizing your notes.

3.Review after class. To consolidate what you have learned, you must review it in a timely manner, reinforce it, and form a habit.

4.The habit of solving problems independently. If you have difficulty learning, you should try to "give it a try" by yourself first. Finish it on your own, taste the sweetness of victory, increase confidence in yourself, and bravely meet the challenge of the next problem.

5.The habit of careful observation and reflection. Each discipline requires itself to be observant. It is also necessary to develop the habit of thinking while observing, and to be diligent in thinking while being diligent in observing. Find the problem yourself, ask the problem, and solve the problem.

6.Actively read and write habits. Reading is the main channel for acquiring knowledge, and on the basis of repeated reading of textbooks, we should widely absorb extracurricular knowledge and information, and develop the habit of active reading.

Reading and writing are both rigorous training in cognitive skills such as observation, thinking, and imagination, and they are mutually reinforcing. The writing process is still a training in the use of language and writing skills, so it is necessary to develop the habit of writing diligently.

7.Develop the habit of active learning. Habits don't happen overnight.

In short, it is a process of accumulation, the more you know, the better you learn, so memorize more and choose your own learning method. Good luck with your studies!

Be sure to take careful notes, do more self-study and make a study plan.

Let the original gas mixture have Xml for NO2 and 30-x ml3NO2+H2O==NO+2HNO3

x x 3 has x 3+30-x==16

x==21ml

So NO2 21ml, NO9ml

NO2 accounts for 7 10, NO accounts for 3 10

In this problem, NO2 reacts with water to form NO, while NOs exist stably, and the final gas is NO. The reaction equation is 3NO2+H2O=2HNO3+NO, and it can be seen from the equation that 3 volumes of NO2 are consumed to obtain 1 volume NO, and 2 volumes are reduced. Therefore, the difference method can be used, and it can be seen from the title that the volume of gas before and after the reaction is reduced by 14ml, and from the relationship described above, it can be obtained that NO2 in the original gas is 21ml, NO is 9ml, and all 21mlNO2 is reacted to obtain 7mlNO, so the remaining gas after the reaction is 9+7=16mlNO.

Hello: For this kind of chemistry problem with reduced volume and reduced (or increased) mass, we often use the difference method to calculate!

Let the volume of NO2 in the gas mixture be x

3no2+h2o==no+2hno3 △v3 1 2x 30ml-16mlx=21ml

Then there are: V(NO)=30ML-21ML=9ML Answer: The volume of NO2 in the mixture is 21ml, and the volume of NO is 9ml.

Hope it helps, thank you!

1 All answers: Ca(OH)2+(NH4)2SO4=CASO4+2H2O+2NH3, the molecular weight of calcium hydroxide is: 74, then the amount of 10 grams of calcium hydroxide is: 10 74 = The molecular weight of ammonium sulfate is:

132.Then the amount of 10 grams of ammonium sulfate is , and in this reaction, the reaction ratio of calcium hydroxide and ammonium sulfate is: 1 to 1, obviously, the reaction of calcium hydroxide is excessive, so the reaction is based on the amount of ammonium sulfate substance, then the amount of ammonia produced can be calculated as:

Under the standard condition, the volume of 1mol of ammonia is , so the volume of ammonia produced is: , the first question answer is completed;

Question 2: If all these NH3 are absorbed by the H2SO4 solution, that is, all the ammonia produced by the first step reaction is incorporated into the sulfuric acid, so it can be calculated that the mass of sulfuric acid increased is the mass of ammonia, and the molecular weight of ammonia is 17, so the calculation formula is: grams;

Handmade, I hope you are satisfied!

Ca(OH)2+(NH4)2SO4=CASO4+NH3+H2O mass Mass 110 10 x First calculate whether there is more than the reaction between Ca(OH)2 and (NH4)2SO4, and then take the mass of the material that is completely reacted and calculate it, and you can calculate X, which is the answer to the first question.

2nh3+h2so4=(nh4)2so4

2 Quality. x y

I can't remember the molecular mass, so I can't figure it out for you, but the idea tells you that you can do the math yourself.

It really doesn't work, you can hi me and tell me the quality.

1.（nh4)2so4+ ca(oh)2 = caso4+ 2nh3 + 2h2o

132 88 2mol

10g x y

x= 880/132g y= 20/132 mol

Volume 20 132 = 112 33 l under surface conditions

2.The increased mass is the mass of NH3, which is 20 132 mol 17g mol = 85 33 g
