质量守恒定律是中学化学的重要定律之一,利用质量守恒定律可以解决许多中学化学试题,但是如果对质量守恒定律理解不透会走进许多误区。一、质量守恒定律的理解误区一:用以解释物理变化中的质量问题。例如:常温下把10g食盐完全溶解在70g
The law of conservation of mass is one of the important laws of chemistry in middle schools. The use of the law of conservation of mass can solve many middle school chemistry problems, but many misunderstandings can come into being if the law of conservation of mass is not understood. First, the understanding of conservation of mass Misunderstanding one: to explain the quality of the physical changes. For example: 10g salt at room temperature completely dissolved in 70g
