利用化学方程式加合的办法来处理某些实际问题,对学生理解化学反应的实质和帮助他们记忆化学方程式甚有好处。但化学方程式的“相加”是有一定局限性的,如果超出适用范围,会导致错误。
The use of chemical equations to ameliorate certain practical problems is helpful for students to understand the nature of chemical reactions and to help them memorize chemical equations. However, the “adding” of chemical equations has certain limitations. If it exceeds the scope of application, it will lead to errors.
