在初中化学总复习中,同学们在教师的指导下,通过全面的、系统的、有针对性的复习和训练,达到巩固记忆、加深理解的目的。一、专题复习,思路清晰 初中化学内容比较零散,若根据知识体系,分成专题,进行总复习,则会收到良好的效果。 通常把初中化学分为四个专题: 第一专题是基本概念和基础理论;第二专题是元素及其化合物,氧化物、酸、碱、盐及其相互关系;第三专题是化学实验;第四专题是化学计算。
In the review of junior high school chemistry, under the guidance of teachers, the students achieved comprehensive memory and deepening understanding through comprehensive, systematic, and targeted review and training. First, the topic review, clear thinking junior high school chemical content is relatively fragmented, according to the knowledge system, divided into topics, conduct a total review, you will receive good results. Junior high school chemistry is usually divided into four topics: the first topic is basic concepts and basic theory; the second topic is elements and their compounds, oxides, acids, alkalis, salts and their mutual relations; the third topic is chemical experiments; The four topics are chemical calculations.
