众所周知的元素化合物知识是中学化学学习的主干内容,是学生学习化学基本概念、基本理论、化学实验的基础与素材,高中化学(含选修),元素化合物占了三分之一,而基本理论、化学实验和化学计算实际上是对元素化合物在“性”和“量”上的研究,有机化学实际上是对碳元素的化合物的系统研究。 Well-known elemental chemical knowledge is the backbone of secondary school chemistry, is the basic concept of learning chemistry, basic theory, the basis and material of chemical experiments, high school chemistry (including elective), elemental compounds accounted for one-third, and the basic theory, Chemical experiments and chemical calculations are actually the study of the elemental compounds in the “” and “amount”, organic chemistry is actually a systematic study of carbon compounds.
