科学研究必须要解决的一个问题就是对研究对象的合理分类,分类的依据不同,就会得到不同的结果.在高考总复习中,有必要对中学阶段所学化学反应的分类进行梳理,比较各种分类方法的本质和联系,构成化学反应分类的网络,形成完整的知识系统.一、无机反应的分类1.四种基本类型在初中阶段,根据反应物和生成物的类别和反应前后物质种类的多少把化学反应分为四种基本类型.用A、B、C、D或其
One of the problems that must be solved in scientific research is that the reasonable classification of the subjects and the different basis of the classification will result in different results.In the review of the college entrance examination, it is necessary to sort out the classification of the chemical reactions studied in the middle school stage, The nature and connection of species classification methods constitute a network of chemical reaction classification to form a complete knowledge system I. Classification of inorganic reactions 1. Four basic types In the junior middle school, according to the type of reactants and products and the types of substances before and after the reaction The number of chemical reactions divided into four basic types with A, B, C, D or its
