First of all, it is meaningful to teach chemistry by yourself. Chemistry is a natural science based on experiments. Many people call chemistry "central science", but this is an inaccurate concept. It is a science that studies the composition, structure, properties, changes and synthesis laws of matter. This is the core foundation of chemical change and western science.

Chemistry plays an important role in our understanding and utilization of matter. The universe is made of matter, and chemistry is one of the main ways and means for human beings to understand and transform the material world. It is a discipline with a long history and full of vitality. It is closely related to human progress and social development, and its achievement is an important symbol of social civilization.

Chemistry is one of the important basic sciences, which develops rapidly with the mutual penetration of physics, biology, geography, astronomy and other disciplines, and also promotes the development of other disciplines and technologies. For example, the research results of nucleic acid chemistry have raised today's biology from the cellular level to the molecular level, and established molecular biology; By analyzing the chemical composition of various stars, the distribution law of elements is obtained, and it is found that there are simple compounds in interstellar space, which provides experimental data for celestial evolution and modern cosmology and enriches the content of dialectics of nature.

Self-study should combine your professional knowledge base, learning purpose and supporting conditions.

Different professional basic levels have different contents for your self-study. If you are a junior high school student, you can learn and popularize college chemistry, introduction to modern chemistry, basic knowledge of chemistry and chemical experiments. If you are not a professional, you can directly read the basic books of related majors, which is not as good as Introduction to Coal Chemical Industry and Clean Coal Technology.

If you want to dabble in reading, you can read what you are interested in, and you must study as required if you want to take the exam.

Two suggestions:

1, it is best to have a basin friend to study with or answer your questions;

2. Where there are experiments or internships, you can increase your interest.

I wish you progress in your study!
