质量守恒定律是一项基本的科学定律,其反应的是科学规律,使用好该项基本定律对于化学知识的掌握非常重要。化学反应中必然会遵守该项定律,这是解决各类题目的基本思想。让学生认识到宏观上元素守恒、总质量守恒;微观上原子数量、种类和质量的守恒。质量守恒定律对于化学教学来说非常重要,学生必须要全面的掌握该项基本内容,否则将无法进行下一步的学习。
The law of conservation of mass is a basic scientific law, which reflects the laws of science. It is very important to master the basic knowledge of chemistry by using this basic law. Chemical reaction is bound to comply with the law, which is to solve the basic ideas of various topics. Allow students to recognize the conservation of elements of the macro, the total mass conservation; microscopic atomic number, type and quality of conservation. The law of conservation of mass is very important for chemistry teaching. Students must have complete mastery of this basic content or they will not be able to proceed to the next step of study.
