从近几年化学高考试题来看,每年都会有不同类型的化学计算题出现,其中化学反应、反应速率及平衡常数属于必考内容,有机反应和多步反应的相关计算出现的频率也较高。试题区分度较大,同学们平时要认真研究,强化训练。一、近几年高考计算题变化情况研究现行高考计算题的难度不大,摒弃了传统命题的繁、难、偏、旧,贯彻落实了新课程理念,注重对学生过程与方法的考查,更加重视对思维逻辑性、敏捷性、发散性和创造性以及相关知识的运用能力的 Judging from the chemistry examination questions in recent years, there will be different types of chemical calculations each year. The chemical reactions, reaction rates, and equilibrium constants are mandatory, and the organic and multi-step responses are relatively frequent. . There is a greater degree of discrimination between the questions. The students must seriously study and strengthen the training. First, in recent years, the changes in the calculation of college entrance examination questions The current college entrance examination questions are not difficult to solve, abandon the traditional proposition of the complex, difficult, partial, old, implement the new curriculum concept, pay attention to the students process and methods of examination, more Emphasizes the ability to use logic, agility, divergence, creativity, and related knowledge
