一、本节的地位质量守恒定律开始了从生成何种物质向生成多少物质方面的过渡,引导学生从量的方面去研究化学反应的客观规律,为化学方程式书写及化学方程式计算的教学做好理论准备。本节是学好本章的基础,也将对全部初中化学乃至今后的化学学习起到至关重要的作用。二、教育
1. The status of conservation in this section begins with the transition from what kind of substance to how much material it produces, guides students to study the objective laws of chemical reactions from the aspect of quantity, and does a good job in the teaching of chemical formula writing and calculation of chemical equations. Theoretical preparation. This section is the basis for the study of this chapter and will also play a crucial role in the chemistry study of all junior secondary schools. Second, education
