化学方程式的配平就是为了使反应式符合质量守恒定律,在式子左、右两边的化学式前配上适当的系数,使式子中每一种元素在左、右两边的原子总数都相等.所以化学方程式的配平是书写化学方程式的重要步骤,正确掌握配平技法显得尤为重要.现介绍五种常用的配平技
The trimming of the chemical equation is to make the reaction conform to the law of conservation of mass, and the right and left sides of the formula are accompanied by appropriate coefficients so that the total number of atoms on each side of the left and right sides of each element is equal. The trimming of the chemical equations is an important step in writing chemical equations. It is particularly important to master the trimming techniques correctly. Now introduce five commonly used trimming techniques.
