化学计算是中学化学的重要内容。化学计算不是一种单纯的数学运算,其任务是从定量的角度来探究物质的性质及其变化规律。所以,通过化学计算的学习,一方面可以掌握化学计算的技能,另一方面还可以加深对有关化学知识的理解,发展思维能力,提高分析问题和解决问题的能力。综观近几 Chemical calculations are an important part of middle school chemistry. Chemical calculation is not a simple mathematical operation. Its task is to explore the nature of matter and its changing rules from a quantitative perspective. Therefore, through the study of chemical calculations, one can master the skills of chemical calculations on the one hand, and on the other hand, it can deepen the understanding of relevant chemical knowledge, develop thinking skills, and improve the ability to analyze problems and solve problems.
