There are four basic courses in chemistry: inorganic chemistry, organic chemistry, physical chemistry, and analytical chemistry.

1. Inorganic chemistry is the science that studies the composition, properties, structure and reactions of inorganic substances, and it is the oldest sub-discipline in chemistry. Inorganic substances include all chemical elements and their compounds, with the exception of most carbon compounds.

2. Organic chemistry is divided into natural organic chemistry, general organic chemistry, organic synthetic chemistry, metallic and non-metallic organic chemistry, physical organic chemistry, bioorganic chemistry, and organic analytical chemistry.

3. The main theoretical pillars of physical chemistry are thermodynamics, statistical mechanics and quantum mechanics. Thermodynamics and quantum mechanics are applicable to microscopic systems, and statistical mechanics is the bridge between the two. In principle, statistical mechanics methods can be used to infer or calculate the macroscopic phenomena of matter through the microscopic data of individual molecules and atoms.

4. Analytical chemistry is a science that studies the analysis methods and theories of chemical information such as the composition, content, structure and morphology of substances, and is an important branch of chemistry.

Extended Materials. 1. Research content of inorganic chemistry.

Gather facts. Methods of collection include observation and experimentation. Experiments are observations under control conditions. Chemistry research attaches great importance to experiments, because the chemical changes in nature are very complex, and it is not easy to obtain the essence of things through direct observation.

Whether it is an observation or an experiment, the facts gathered must be accurate and accurate. Various operations in chemical experiments such as precipitation, filtration, cauterization, weighing, distillation, titration, crystallization, extraction, and many more.

2. Research content of organic chemistry.

Organic synthesis is the study of the synthesis of organic compounds from simpler compounds or elements through chemical reactions.

3. Physical and chemical research content.

The generally accepted research content of physical chemistry can be roughly summarized into three aspects: the macroscopic equilibrium properties of chemical systems.

The microstructure and properties of a chemical system, the dynamic nature of a chemical system.

4. Research content of inorganic chemistry.

Analytical chemistry is an important branch of chemistry, which mainly studies what elements or groups are in a substance (qualitative analysis); the quantity or purity of each ingredient; How atoms are joined together into molecules, how they are arranged in space, and so on.

1.Inorganic chemistry is the study of inorganic compounds, and is an important branch in the field of chemistry.

2.Organic chemistry, also known as the chemistry of carbon compounds, is the science that studies the composition, structure, properties, preparation methods and applications of organic compounds.

3.Analytical chemistry is a science that studies the analysis methods and theories of chemical information such as the composition, content, structure and morphology of substances.

4.Structural chemistry is a branch of chemistry that studies the interrelationship between the molecular configuration and composition of matter and the interaction of structure and various motions at the atomic and molecular level.

5.Physical chemistry is a discipline that studies the nature and behavior of chemical systems based on the principles of physics and experimental techniques, and discovers and establishes special laws and prudence in chemical systems.

6.Polymer chemistry is an emerging comprehensive discipline that studies the synthesis, chemical reaction, physical chemistry, physics, processing and application of polymer compounds.

Chemistry refers to the study of chemistry. Serve the potato beard

The content of chemistry is generally divided into seven categories, including biochemistry, organic chemistry, polymer chemistry, applied chemistry and chemical engineering, physical chemistry, and inorganic chemistry, with a total of 80 items, and actually includes seven sub-disciplines.

Before the 20s of the 20th century, chemistry was divided into four branches: inorganic chemistry, organic chemistry, physical chemistry and analytical chemistry.

Knowledge and skills required for chemistry majors:

1. Master the basic theories and basic knowledge of mathematics and physics.

2. Master the basic knowledge, basic principles and basic experimental skills of inorganic chemistry, analytical chemistry (including instrumental analysis), organic chemistry, physical chemistry (including structural chemistry), chemical engineering and chemical drawing.

3. Understand the general principles and knowledge of similar majors.

4. Understand the national policies and regulations on science and technology technology, chemical-related industries, intellectual property rights, etc.

5. Understand the theoretical frontiers, application prospects, the latest development trends of chemistry, and the development status of chemistry-related industries.

1. The four basic reaction types are very important types of chemical reactions, which are chemical reaction reaction, decomposition reaction, displacement reaction and metathesis reaction.

2. Chemical reaction: Chemical reaction refers to the reaction of two or more substances to form a new substance. Some of the reactions are redox reactions, and some are non-redox reactions.

In addition, chemical reactions generally release energy. It can be abbreviated as a+b=ab.

3. Decomposition reaction: The reaction of two or more other substances generated by one substance is called decomposition reaction. The abbreviation is divided into two and is expressed as ab=a+b. Only the chemical compound can undergo a decomposition reaction.

4. Displacement reaction: a chemical reaction between an element and a compound to form another element and a compound, including the reaction between metal and metal salt, the reaction between metal and acid, etc. It can be abbreviated as ab+c=a+cb

5. Metathesis reaction: the reaction of two compounds to generate two other compounds by exchanging components with each other. Its essence is:

The two substances that undergo metathesis reaction exchange ions with each other in the aqueous solution, and combine into substances that are difficult to ionize - precipitation, gas, and water (weak electrolyte), so that the ion concentration in the solution decreases and decreases, and the chemical reaction is carried out in the direction of the decrease in ion concentration. It can be abbreviated as ab+cd=ad+cb.

1. Chemistry is a kind of natural science, which studies the composition, properties, structure and change laws of matter at the molecular and atomic levels; The science of creating new matter. The world is composed of matter, and chemistry is one of the main methods and means used by human beings to understand and transform the material world.

Learning of Chemistry Concepts:

The concept of chemistry is the most basic element of the discipline of chemistry, and it is all the basic parts that make up the vast machine of chemistry. A series of basic theories in chemistry are made up of these "basic parts". Therefore, to learn chemistry, we must first pay attention to the learning of chemical concepts.

In order to grasp chemical concepts, students will make full use of their senses and perceptions, engage in active thinking activities, and use their comprehension to grasp the content of concepts. For example, if the three concepts of atoms, elements, and elements cannot be thoroughly understood, their essential properties are easily confused. Atoms are the smallest particles in chemical changes, elements are the general term for the same class of atoms with the same number of nuclear charges, and substances composed of the same kind of elements are called elementals.

Therefore, it is necessary to analyze these three concepts dialectically and comprehensively, to see both the differences and the connections, to clarify the connotation and extension of these three concepts, and to deepen our understanding of the concepts.

The second step after understanding the connections and differences between concepts is to compare, classify, and summarize all the concepts learned in chemistry to form a large conceptual network, and then consciously memorize them. After that, every time I learn a new concept, I immediately analyze it and put it into my own knowledge system, that is, this conceptual network. If we can consciously memorize in this way, the connections between the concepts will become more and more numerous, and the meanings and generalizations of the concepts will be richer.
