难道化学反应方程式也能象代数方程式一样相加吗?这个问题好多同志感到陌生。其实在一定条件下它确是可“相加”的。在一些无机化学教科书中可找见这方面的例子。对一些特殊的化学反应,用“相加”化学方程式的方法进行讲解,倒是一个行之有效的方法,它可以帮助学生理解化学反应的全过程。下面只就“相加”条件及方法列举十例,谈谈这个问题。不妥之处,请读者批评指正。
Can the chemical reaction equations be added together like algebraic equations? Many comrades are unfamiliar with this question. In fact, under certain conditions, it is really possible to “add”. Examples can be found in some textbooks on inorganic chemistry. For some special chemical reactions, using “adding” chemical equations to explain, it is an effective method, it can help students understand the whole process of chemical reactions. In the following, only ten examples of the “adding” condition and method will be mentioned and the issue will be discussed. Inappropriate, please readers criticized and corrected.
