“将化学问题抽象为数学问题,利用数学工具,结合化学知识,通过计算和推理,解决化学问题的能力”是化学科高考考试说明规定了的解答化学试题应具备的思维能力要求.借助数学思想方法解答化学试题可以培养思维的严密性、深刻性和逻辑性.可见,在有些化学试题中如果我们把数学思想方法和化学思维技巧融合在一起,就可达到事半功倍的效果.现作如下举例说明.例1将0.2 mol KMn O4在一定温度下加热后生成a mol “Abstraction of chemical problems as mathematical problems, the use of mathematical tools, combined with chemical knowledge, through the calculation and reasoning to solve the problem of chemical ability ” is a chemical college entrance examination examinations prescribed answer chemistry questions should have thinking ability requirements. Mathematical thinking and methods to answer chemistry questions can cultivate the rigor, profoundness and logic of thinking, so we can see that in some chemistry questions, if we combine mathematical thinking methods and chemical thinking skills, we can achieve a multiplier effect. For example, Example 1 0.2 mol KMn O4 heated at a certain temperature to generate a mol
