通过化学计算,能使学生从量的方面来理解物质及其变化的规律,并获得化学计算的基本技能,加深和巩固对化学基本概念、化学基本理论、元素化合物等知识的理解和掌握,巩固和熟悉化学用语;发展学生逻辑推理与抽象思维;培养学生分析问题和解决问题的能力。化学计算又是教学中理论与实际相结合的重要环节,工农业生产和科学实验研究都离不开有关的计算。因此,化学计算技能,不但是学生进一步学习所必需,也是今后从事工农业生产及科学实验研究必备的基本技能之一。
By stoichiometry, students can understand the law of matter and its variation from the aspects of quantity, obtain the basic skills of stoichiometry, deepen and consolidate the understanding and mastery of the basic concepts of chemistry, basic chemical theory, elemental compounds and other knowledge, and consolidate And be familiar with chemical terms; develop students 'logical reasoning and abstract thinking; develop students' abilities to analyze and solve problems. Chemical calculation is an important part of the combination of theory and practice in teaching. Both industrial and agricultural production and scientific experimental research can not be separated from relevant calculations. Therefore, the stoichiometric skills are not only necessary for students to learn further, but also one of the basic skills necessary for future industrial and agricultural production and scientific experiments.
