Chemical equations, also known as chemical reaction formulas or chemical reaction equations.
A chemical reaction equation is a symbolic representation of a chemical reaction that is used to describe the different chemical reactions between various substances.
When writing chemical equations, the reactants are on the left and the products are on the right. The coefficient before reactant and product is the absolute value of the stoichiometric number.
Writing chemical equations should abide by two principles: first, it must be based on objective facts, and it is absolutely impossible to conjecture or 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.

Chemical Reaction Equations
A chemical equation, also known as a chemical reaction equation, is a formula that uses a chemical formula to represent a chemical reaction. Chemical equations reflect objective facts. The formula that uses the chemical formula (organic matter in organic chemistry generally uses the simple structure formula) to express the chemical reaction of a substance is called a chemical equation.
The chemical equation not only indicates the reactants, products, and reaction conditions. At the same time, the stoichiometric number represents the quantitative relationship between the reactants and the product substances, and the mass relationship between the substances can also be expressed through the relative molecular mass or relative atomic mass, that is, the mass ratio between the substances. For gas reactants and products, the volume ratio can also be obtained directly from the stoichiometric number.

When writing chemical equations, the reactants are on the left and the products are on the right. The coefficient before reactant and product is the absolute value of the stoichiometric number.
There are two principles to be observed in writing chemical equations: first, it must be based on objective facts, and it is absolutely impossible to conjecture or fabricate substances and chemical reactions that do not actually exist; Second, it is necessary to abide by the law of conservation of mass, and the types and numbers of the original Zheng Hezi on both sides of the equal sign must be equal.
