在化学当中,计算题往往作为压轴题放在试卷的最后.那么,如何解答好计算题就成了与竞争对手拉开差距的一个关键.可是,有的计算题设计十分巧妙,题中除了必要的文字叙述外无一个数字出现,但结果却又是具体的数值,实际上这就涉及了一系列特殊思想及方法的运用,现浅谈如下: 一、设一法:既恰当选择研究对象,将其设成一个基本单位,进行解答.解答的关键是如何 In chemistry, calculation questions are often placed at the end of the paper as finale questions. Then, how to solve good calculation questions becomes a key to opening the gap with competitors. However, some calculation questions are ingeniously designed. None of the text narratives appear outside of the figures, but the results are actually specific values. Actually, this involves the application of a series of special ideas and methods. Now we will talk about the following: Set it as a basic unit and answer it. The key to answer is how
