差量法是利用化学反应前后某些成分在物质的量、质量、体积等的变化来进行解题的有效方法.这种方法很多时候也给大家的解题带来便利,可将两个反应的计算合为一个.在高中化学解题过程中常常要用到差量法,以减少大量的计算过程.而我们在教学时要引导学生恰当使用差量法,为解题服务.在学习时要注重归纳与分析,总结各个类型的差量法
Difference method is to use some of the chemical composition before and after the reaction in the amount of material, quality, volume, etc. to solve the problem of effective methods.This method often give us the convenience of solving problems, you can two reactions The calculation of a combination of high school chemistry in the process of solving the problem often to use the difference method to reduce a large number of calculation process.We should guide students in teaching the appropriate use of the difference method to solve the problem in learning Should pay attention to induction and analysis, summarizes the various types of difference method
