计算题型在近几年高考试题中频繁出现,主要以选择题或计算型填空题呈现,此类题不仅考查学生对化学反应计算深度及广度的理解程度,同时也考查学生对此知识点掌握的熟练程度和思维的敏捷性及发散性,这类试题的特点是:许多计算型选择题均可用常规解法解答,但往往会出现耗时多,运算步骤繁,出错率高等,如果对此方面知识点理解和掌握的扎实透彻,
Computational questions frequently appear in college entrance examination papers in recent years, mainly in the form of multiple choice questions or computational blanketing questions. These questions not only examine students ’understanding of the depth and breadth of chemical reactions, but also examine students’ mastery of this knowledge Of the proficiency and thinking of the agility and divergence, the characteristics of such questions are: Many computational choice can be used to solve the conventional solution, but often time-consuming and complex, complicated steps, higher error rate, if this aspect Understanding and mastery of knowledge points solid and thorough,
