质量守恒定律是所有化学反应遵循的普遍规律,是化学方程式的书写和计算的理论依据,在初中化学里有着承上启下的作用,它对整个初中化学的学习,起到了至关重要的作用.它的应用贯穿于整个中学化学.然而由于学生从量的角度认识化学反应观念的缺识,使质量守恒定律的应用难上加难.下面结合
The law of mass conservation, a universal law followed by all chemical reactions, is the theoretical basis for the formulation and calculation of chemical equations. It plays an important role in the chemistry of junior middle schools and plays a crucial role in the chemistry of junior middle schools. Application runs through the entire secondary chemistry. However, due to the lack of understanding of the concept of chemical reaction from the perspective of students, the application of the law of conservation of mass harder.
