What should I pay attention to when studying chemistry?

1.Laying a good foundation The main thing is to memorize the basic knowledge in the textbook. Teach you how:

Copy down important concepts from the textbook on a blank sheet of paper and make a few important blanks, and then read them out on the paper without looking at the textbook. Or ask a classmate and ask one question at a time. That's what I've done before, and it works very well.

2.Be sure to listen carefully in class 3And most importantly, it's important to do more hands-on experiments.

Think more about why the phenomenon is happening, because that's the point of the exam. You must be able to do the experiments in the textbook, and you must remember the phenomena clearly. Generally, if you do it carefully, you can remember it.

This will help you remember the basics better.

<> the role of learning chemistry is as follows:

1. The purpose of studying chemistry is to improve the cognitive ability of things.

Understanding the basic common sense and phenomena that are closely related to daily life, so as to analyze problems with scientific methods, is to form a good thinking ability.

The key to improving quality is an important method.

2. Understand the principle of chemical change, understand some chemical phenomena in life and production, and control chemical change to make it develop in the direction of human benefit.

3. It can refine the substances that originally existed in nature, and can also produce substances that did not exist in nature. It can help people develop new materials, research new energy sources, study the signs of life, rationally use resources, prevent pollution and protect the environment.

Promote agricultural production and human health.

4. Chemistry is one of the main methods and means used by people to understand and transform the material world. Chemistry is a discipline with a long history and vitality, and the achievements of chemistry are important symbols of social civilization.

1. There are two main levels to learn chemistry well, one is "fine", and the other is "comprehensive analysis". Abstracting all the chemistry content that has been learned is nothing more than some basic theories. Sort out the general content of each part, build the skeleton, then fill in the flesh, and then use nerves and blood vessels to connect the parts to form an organic whole.

Because there are many trivial knowledge points in chemistry, it needs to be accumulated repeatedly to enrich the organic connotation of this knowledge. The chemistry exam focuses on comprehensive ability, and this comprehensive ability can only be improved through ordinary training, and it is of little significance to rely on pre-exam assault.

To do well in chemistry, we should pay attention to the cultivation of the ability to take the exam. In the process of comprehensive analysis, it is necessary to pay close attention to the "double base," cross-link and form a network, and establish all kinds of knowledge into "blocks." All chemistry can be broadly summarized into the following six parts.

Review the training according to the "block", choose some questions to do appropriately, especially for the questions that you did wrong or will not do at that time, carefully analyze them, check and fill in the gaps, and there will be good results.

1 Basic concept "block". This section includes five knowledge lines (or small systems) such as material composition and classification line, property change line, chemical terminology line, dispersion system line, and chemical quantity line.

2 Basic Theory "Block". This section includes structural theory (atomic structure, molecular i.e. chemical bond theory, crystal structure theory) and periodic law of elements, contemporaneous table lines, electrolyte solution (including oxidation-reduction theory) lines, chemical reaction velocity and chemical equilibrium theory lines. The theoretical block is the soul of chemistry.

3 "Blocks" of knowledge of elements and their compounds. This is the cornerstone of chemistry and can be divided into metallic and non-metallic wires, unified in the periodic system.

4 Organic matter "blocks". At the heart of this piece are the lines of hydrocarbons and their derivatives, with an emphasis on structure and chemical properties, which in turn are functional groups and chemical bonds directly related to functional groups.

5 Calculate the "block". This part runs through all parts of chemistry, and it is necessary to master the basic types, problem-solving rules and problem-solving skills.

6 Basic Experimental "Blocks". This section fully reflects the characteristics of chemistry. Including instruments, basic operations, preparation, identification (determination), purification, quantitative experiments, reagent storage, accident handling, etc.

Chemistry is known as the liberal arts in science, and the main thing is to remember more and read more!
