化学计算是化学教学中的一个重要组成部分。通过化学计算能进一步巩固已学过的基本概念和基本理论,特别是混和物的计算题,涉及的反应多,物质间量的关系错综复杂,题型的变化多种多样。解好这类题,能培养学生的逻辑思维能力和综合能力。所以,多年来高考化学试题中,化学计算都占有相当的比重。下面就有关题型的计算,谈谈方法和技巧。
Chemistry is an important part of chemistry teaching. By stoichiometry, we can further consolidate the basic concepts and basic theories we have learned, especially the computational problems of mixtures. The reactions involved are complex and the relationships between the quantities of materials are complicated. The types of questions vary widely. Solve these problems, can develop students’ logical thinking ability and comprehensive ability. Therefore, over the years the entrance exam chemistry questions, chemical calculations account for a considerable proportion. The following questions on the calculation, talk about methods and techniques.
