化学计算题是一种综合性较强的试题,它既考查学生的化学基础知识,又考查学生的数学推算能力。有关题型可以是计算题,也可以是选择题或填空题,而后两种题型由于只需答案而不需详细过程,故存在巧解、速解方法,现介绍两种。一、假设特殊值,巧解“无数题”无数据计算题是一种特殊类 The chemical calculation question is a kind of comprehensive test question, it examines the student’s chemistry basic knowledge, but also examines the student’s mathematical projection ability. The relevant question type can be a calculation question, or a multiple choice question or a blank answer. Since the latter two questions do not require a detailed process because they only require answers, there are clever solutions and quick solutions. Two kinds of questions are introduced here. First, assuming special values, clever solution “numerous questions” no data calculation is a special class
