现行粤教版九年级化学教材中“第八章生活中的酸、碱、盐”是整个初中化学教材中的重点和难点,也是中考的重点。其中单质、氧化物、酸、碱和盐的化学性质及其互变规律也是本章的核心内容,对今后进一步探究元素化合物性质以及应用化学方程式计算等知识显得尤为重要。一、帮助学生探究化学反应中的规律性知识在结束第八章内容需进行复习、总结和归纳时,引导学生共同探究单质、氧化物、酸、碱、盐之间的联系,把能发生反应的连线,形式可以使开放式的,
The current ninth edition of Guangdong Education Edition textbook “eighth chapter life acid, alkali, salt,” is the entire junior high school chemistry textbook focus and difficulty, but also the focus of the exam. Among them, the chemical properties of elemental, oxide, acid, alkali and salt and their interdependencies are also the core contents of this chapter. It is particularly important to further explore the properties of elemental compounds and the application of chemical equation calculation in the future. First, to help students explore the regular knowledge of chemical reactions Chapter VIII of the contents of the end of the need to review, summarize and summarize, guide students to explore the simple substance, oxide, acid, alkali, salt, the link between the reaction to occur The connection can be made in the form of open,
