复分解反应是化学反应中的一个重要基本类型。应用复分解反应的定义及条件书写化学反应方程式,是初中化学的一个重点和难点。但由于教材中对复分解反应的条件只是从生成物方面作了说明,而没有涉及反应发生时对反应物的要求,致使多数学生在书写化学方程式时,只是一味去“交?
Metathesis reaction is an important basic type in chemical reaction. The definition and conditions of the application of metathesis reactions Writing chemical reaction equations is a key and difficult point in junior middle school chemistry. However, because the conditions for the metathesis reaction in the teaching materials are only described in terms of products, and do not involve the requirements for the reactants when the reaction occurs, most students only just go to “comply” when writing chemical equations.
