解有关化学反应的计算题,首先应分析在给定的条件下,化学反应过程实际情况,写出有关的化学方程式,(后面例题作为已知未作分析),然后着重分析题目中所给数(据)量(已知条件);找出符合题目要求建立方程(比例式)的数(据)量。化学式表示的量都是相关纯净物的数(据)量。若题目给出多
To solve the calculation questions related to chemical reactions, first of all, under the given conditions, the actual situation of the chemical reaction process should be analyzed, and the relevant chemical equations should be written (the latter example is known as unanalyzed), and then the number given in the question is analyzed. (Acquisition) quantity (known condition); Find the number (correspondence) quantity that meets the requirements of the problem and establish the equation (proportional formula). The quantity represented by the chemical formula is the number (correspondence) of the related pure material. If the question is given more
