近年来,化学中考越来越注重题型的多样性和灵活性,目的主要考查同学们反应能力和解题能力。有些比较复杂的题目,如果运用质量守恒定律,将会取到事半功倍的效果。为此,本人对能运用质量守恒定律解答的题目进行归类,分析其解法,供同学们学习时参考。一、利用质量守恒定律确定化学 In recent years, chemistry examinations have become more and more focused on the diversity and flexibility of the questions. The purpose is to examine students’ ability to respond and solve problems. Some of the more complex topics, if you use the law of conservation of mass, will get a multiplier effect. For this reason, I classify the questions that can be answered by using the law of conservation of mass, and analyze the solutions so that the students can refer to them when they study. First, use the law of conservation of mass to determine the chemistry
