1质量守恒质量守恒定律是在化学反应中,参加反应的各物质的质量总和等于生成的各物质的质量总和.将这一定律运用于解决化学问题的方法就是质量守恒法.
1Conservation of mass conservation The law of mass conservation is that in chemical reactions, the sum of the mass of each substance participating in the reaction is equal to the sum of the mass of each substance produced. The method of applying this principle to the solution of chemical problems is mass conservation.
