近几年来全国各地化学中考试题中的计算题,逐步走出了偏、繁、难的误区,由过去单纯考查各种化学复杂计算能力,变为现在重点考察运用简单计算解决实际问题的能力。在近几年中考阅卷中,我发现计算题的难度虽然逐年降低,但是同学们的得分率却仍然不高。问题到底出在哪儿了呢?下面我就帮助同学们 In recent years, the calculation questions in the chemistry examination questions in various parts of the country have gradually gone beyond the biases of partiality, complexity, and difficulty. From the simple examination of various chemical complex computational capabilities in the past, they have now become the focus of investigating the ability to use simple calculations to solve practical problems. In the examination papers in recent years, I found that although the difficulty of calculating problems has decreased year by year, the scores of students are still not high. Where is the problem? Below I will help the students
