今年高考化学试题能紧扣中学化学教材,基本题占绝大多数,许多试题的答案都可以从中学课本中直接找到,考查的知识面较宽,重点较突出,可以说中学化学教材的主要内容在试题中均有所反映。例如:基本理论中物质结构、化学平衡、电离平衡占试题总份量的近三分之一;无机和有机化学方程式共考了十八个,其中包括氧化物、碱、酸、盐的相互关系,氧化还原反应,重要的无机制备反应以及有机中包括取代、水解、消去、加聚、缩聚和氧化还原等多种反应类型;化学实验方面不仅考查了基本的实验操作,也考查了定量实验中的误差分析;化学计算方面既有常规计算,也注意考查了学生容易混淆的概念,如分子量与摩尔质量,当量定律,当量浓度与克当量数、摩尔数等等。从总的来看,今年我省考生之间的化学知识水 This year’s college entrance examination chemistry test questions can be closely linked to middle school chemistry textbooks. The basic questions account for the vast majority. Many of the answers to the questions can be found directly from the middle school textbooks. The knowledge of examinations is wider and the emphasis is more prominent. It can be said that the main contents of middle school chemistry textbooks Reflected in the test questions. For example, in the basic theory, the material structure, chemical balance, and ionization balance account for nearly one-third of the total weight of the test items; eighteen inorganic and organic chemical equations have been examined, including the correlation among oxides, alkalis, acids, and salts. Oxidation-reduction reactions, important inorganic preparation reactions, and organic reactions include substitution, hydrolysis, elimination, polyaddition, polycondensation, and redox reactions; chemical experiments not only examine basic experimental operations, but also examine quantitative experiments. Error analysis: There are both routine calculations for chemical calculations and attention to the concept of confusing students, such as molecular weight and molar mass, equivalent law, equivalent concentration and gram equivalent, number of moles, and so on. From a general point of view, this year’s chemical knowledge among candidates in our province
