一、要记住复分解反应的概念由两种化合物相互交换成分,生成另外两种化合物的反应,叫做复分解反应·二、要明确复分解反应的要点1·要明确反应物、生成物的种类和类别:即反应物和生成物都是两种化合物·2·要明确反应前后物质变化的组合形式:即反应是否“互相交换成分”·从化 First, keep in mind that the concept of metathesis reaction consists of the exchange of components by two compounds, the reaction of the formation of two other compounds, called the metathesis reaction. Second, we must clarify the main points of the metathesis reaction. 1. Identify the types and types of reactants and products. : That is, the reactants and the products are both compounds. 2. The combination of the substances before and after the reaction must be clearly defined: ie, whether the reaction “exchanges components” or not.
