学习中学化学过程中,学生对于配平化学反应方程式是感到比较困难的,所以教师在教学过程中要注意介绍配平方法,并通过练习逐步熟练掌握。配平化学反应方程式的方法很多,如果能用简单的方法来配平则学生容易掌握、教学效果也好一些,下面举例说明之。 In the middle school chemistry process, students are more difficult to balance the chemical reaction equation. Therefore, teachers should pay attention to introducing the trimming method during the teaching process and gradually master the exercises. There are many ways to balance the chemical reaction equation. If you can use a simple method to balance the level, you can easily grasp and teach the students. Here are some examples to illustrate.
