化学方程式是初中化学教材中一个重要章节,其中又以化学方程式的配平最为关键。只有会配平化学方程式,才能掌握化学反应前后物质的变化和质量关系,从而进一步根据化学方程式进行量的计算。下面,介绍几种初中常用的化学方程式的配平方法,供同学们参考:一、观察法这种方法是对一 The chemical equation is an important chapter in junior high school chemistry textbooks, and the balancing of chemical equations is the most critical. Only the chemical equations will be balanced in order to grasp the changes in the material before and after the chemical reaction and the relationship between the quality, so as to further calculate the amount according to the chemical equation. Below, introduce the trimming methods of several commonly used chemical equations for junior high school students for reference: First, the observation method This method is a
