在高三化学学习和复习过程中,面对沉重的学习压力和紧凑的学习时间情况下,提高效益显得尤为重要.笔者根据自己的复习经验,认为其中很重要的方面,就是通过总结法,不断总结和归类,在解题过程中运用守恒定律,加快解题速度.在化学反应过程中总会发生各种各样的变化,但这些变化都可以归结于物理变化和化学变化的范畴之中.但无论是化学变化还是物理变化,物质和能量都不会凭空产生,抑或凭空消失,这就涉及到了化学中的两个定律——物质守恒定律和能量守恒定律.从
In the senior high school chemistry learning and review process, in the face of heavy learning pressure and compact learning time circumstances, it is particularly important to improve the efficiency of the author.According to my own review experience, I think one of the most important aspects is through the summary of the law, continue to summarize And classification, the use of conservation law in the process of solving problems, to speed up the problem-solving speed in the chemical reaction will always occur a variety of changes, but these changes can be attributed to the physical changes and chemical changes within the category. However, whether chemical or physical changes, material and energy are not generated in the air, or disappear out of thin air, which involves the two laws of chemistry - the law of conservation of matter and the law of conservation of energy from
