化学的学习,是以理论知识与实践相结合的学科。同时也是和生活息息相关的一门课程。在高中化学的学习过程中,化学的能源是学习的重点,也是理解高考的重点。大部分同学在解析此类题目的过程中或因对概念掌握牢固、化学反应式记忆混乱等原因丢失分数。本文针对几种常见的题型,阐述化学反应中的反应热的计算问题。 Chemical learning is a discipline that combines theoretical knowledge and practice. It is also a course closely related to life. In the learning process of high school chemistry, chemistry energy is the focus of learning, but also the key to understanding the college entrance examination. Most of the students lost scores in the process of analyzing such problems or due to the fact that they had a solid grasp of the concepts, chemical reaction-type memory confusion and other reasons. This article addresses the calculation of the reaction heat in chemical reactions for several common questions.
