初中化学课本上出现的化学方程式非常多,大多数学生记不住、不会写.其实,这些化学方程式大多数是有规律的,只有及少数需要死记硬背,大多数方程式可以通过反应类型、反应条件、反应本质去理解和书写.初中化学反应类型分为基本反应类型和非基本反应类型.一、基本反应类型化学方程式的书写和记忆方法基本反应类型有四大类,分别为化合反应、分解反应、置换反应及复分解反应.
Most of the students can not remember, can not write .In fact, most of these chemical equations are regular, and only a few need rote memorization, most of the equations can be through the reaction type, Reaction conditions, the nature of the reaction to understand and write junior high school chemical reaction types are divided into basic types of reactions and non-basic types of reactions, the basic reaction types of writing and memory methods of chemical equations There are four basic types of reactions, namely, chemical reactions, Decomposition reaction, displacement reaction and metathesis reaction.
