1, the elective chemistry textbook * * * is divided into six chapters, which respectively introduce chemical reaction and its energy change, material structure basis, material change and energy change in chemical reaction, chemical reaction rate and chemical equilibrium, ion balance in aqueous solution and the structure and properties of organic compounds.
2. The first chapter introduces chemical reaction and its energy change, so that students can understand the energy change in chemical reaction and how to calculate the energy change in chemical reaction. The second chapter introduces the structural basis of matter, so that students can understand the structure of atoms, the formation of chemical bonds and the intermolecular forces. The third chapter introduces the changes of substance and energy in chemical reactions, so that students can understand the types of chemical reactions.
3. The fourth chapter introduces the chemical reaction rate and chemical equilibrium, so that students can know how to control the chemical reaction rate and reach the equilibrium state, and let students know the principle of equilibrium movement and its application in industrial production. The fifth chapter introduces the ion balance in aqueous solution, so that students can understand the ion balance in solution and how to adjust the pH value of the solution.
Chemical related knowledge
1. Chemistry is a discipline that studies substances and their changing laws, involving all levels from micro to macro. The research objects of chemistry include atoms, molecules, ions, compounds and so on. And their properties, composition, structure and changes. Chemical knowledge covers many aspects, including inorganic chemistry, organic chemistry, physical chemistry, analytical chemistry, polymer chemistry and so on.
2. The research contents in these fields are different, but they are closely related to the basic principles and concepts of chemistry. Inorganic chemistry is a subject that studies the chemical properties and changes of inorganic substances, including the properties, composition, structure and changes of elements, compounds, ions and compounds. Organic chemistry mainly studies the structure, properties, synthesis and degradation of organic compounds, as well as their metabolism and reactions in organisms.
3. Physical Chemistry studies chemical phenomena from a physical perspective, including chemical reaction kinetics, thermodynamics and electrochemistry. Analytical chemistry makes quantitative and qualitative analysis of substances through various experimental methods to determine their composition and properties. Polymer chemistry mainly studies the synthesis, properties and uses of polymer compounds.
