我觉得,氧化数法用最小公倍数配平化学方程式,学生难以掌握。若用代数法的“代数方程”取代“最小公倍数”,并打破先确定反应物系数的习惯,就不愁氧化数法的简单化。下面举例说 I think that the oxidation number method uses the least common multiple to balance the chemical equation and it is difficult for students to master. If the algebraic equation “algebraic equation” is used to replace the “Least Common Multiple” and the habit of first determining the reactant coefficient is broken, the simplification of the oxidation number method will not occur. For example below
