In classroom teaching, attention should be paid to reflecting the learning process of students, and the core is the cultivation of students' interests, the inspiration of thinking, and the guidance of learning methods.

This lesson plan is designed with five teaching links: setting questions, student discussion, identification and analysis guidelines, deducing conclusions, and teaching evaluation. A chemical equation, also known as a chemical reaction equation, is a chemical formula that expresses the reflection between different substances. Chemical equations reflect objective facts, so there are two principles to follow when writing chemical equations:

First, it must be based on objective facts, and must not be conjectured out of thin air, and fabricate substances and chemical reactions that do not actually exist; Second, to abide by the law of conservation of mass, the types and numbers of atoms on both sides of the equal sign must be equal.

There are too many, so I still want to buy a tutorial book, which should be all in it.
