二氧化碳是一种独特的气体,具备较为复杂的物理性质以及化学性质。本文以“物质的性质决定物质的用途”和“化学与生产生活相联系”为主题,设计了这方面的案例,希望能够为相关人员提供有益的参考。一、教学目标首先要求学生能够认识CO2的主要化学性质以及物理性质,知道相关的化学反应,让学生知道这种气体的性质能够决定它的用途,使二氧化碳在生产生活中得到了广泛的运用,这样能够提升学生分析、解决实际问题的意识和能力,更好地把握CO2在自
Carbon dioxide is a unique gas with more complex physical and chemical properties. This article is based on the theme of “the substance of the substance determines the use of the substance” and the “chemical and the production of life”, designed a case in this area, hoping to provide useful reference for the relevant personnel. First, the teaching objectives First of all require students to recognize the main chemical and physical properties of CO2, to know the relevant chemical reactions so that students know the nature of this gas can determine its purpose, so that carbon dioxide in the production and life has been widely used, This will enhance students’ awareness and ability to analyze and solve practical problems and better grasp the potential of CO2 in
