浅议化学方程式的配平■武焕业有的学生认为化学方程式只要配平就算对了，其实不然。因为，有的方程式有几种配平形式，所以必须判别哪一种形式是正确的。例如：根据质量守恒定律，这两种不同的配平形式都是可行的。但只要分析问题的化学本质，就可知第二种是错误的。因为... On the balance of the chemical equations ■ Some students in Wu Huanye think that even if the chemical equation is evenly balanced, it is not. Because some equations have several types of trim, it is necessary to determine which form is correct. For example: According to the law of conservation of mass, these two different types of trim are feasible. However, as long as the chemical nature of the problem is analyzed, we know that the second is wrong. because...
