近年的化学高考试题中,加强了定量理性思维能力的考查,无论是分值还是难度都有所增加。可见,将化学问题抽象成为数学问题,利用数学工具,通过计算和推理(结合化学知识),解决化学问题的能力,是命题专家非常关注的.因此,同学们在复习备考中要引起足够的重视.下面提供一例,来帮助同学们复习。 In recent years, in the chemistry examination questions, the examination of quantitative rational thinking ability has been strengthened, both in scores and in difficulty. It can be seen that abstracting chemical issues into mathematics problems and using mathematical tools to solve chemical problems through calculations and reasoning (in combination with chemical knowledge) is a proposition specialist’s concern. Therefore, students should pay enough attention to reviewing the pro forma. Here is an example to help students review.
