碳酸盐和碳酸氢盐是生活中应用比较广泛的盐类,也是高中化学教学中非常重要的知识点,因为它们在组成和性质上有许多相同之处,也有许多不同之处,许多高中化学试题正是利用这些异同点,来考查和巩固学生的基础知识,提升学生的综合能力。以下题第③题的解答为例。一、试题再现为减小和消除CO_2对环境的影响,一方面世界各国都在限制其排放量,另一方面科学家加强了对CO_2创新
Carbonates and bicarbonates are among the most widely used salts in life and are also a very important knowledge point in high school chemistry teaching because they have many similarities in composition and properties and many differences. Many high school chemistry Questions are the use of these similarities and differences to examine and consolidate the basic knowledge of students to enhance the overall ability of students. The following questions the first three questions answer as an example. First, the test questions to reduce and eliminate the impact of CO_2 on the environment, on the one hand all countries in the world are limiting their emissions, on the other hand scientists to strengthen the CO_2 innovation
