一、总体分析 2004年高考理科综合能力测试卷化学科特别突出了对本学科主干知识的测试。如物质结构、元素周期表、离子共存和离子方程式、物质的量、氧化还原反应、溶液的pH和电离平衡、化学反应速率和化学平衡等化学基本概念和基本理论知识,而化学反应与能量及热化学方程式在三套全国卷中都有所涉及,体现了新课程新要求。元素化合物和有机化学考查了物质的推理及转化关系,这是历年高考必考题型,但今年均突出了通过计算定量推断,体现了化学变化中不仅有定性的物质转化关系,还同时存在定量反应关系这一学科特点。对于化学实验着重考查了基本
First, the overall analysis 2004 college entrance examination science comprehensive ability test volume chemistry subjects in particular highlight the knowledge of the subjects of the test. Such as material structure, periodic table of ions, ionic coexistence and ionic equation, amount of substance, redox reaction, solution pH and ionization equilibrium, chemical reaction rate and chemical equilibrium and other chemical basic concepts and basic theoretical knowledge, and chemical reactions and energy and Thermochemical equations are covered in three sets of national volumes, reflecting the new requirements of the new curriculum. Elemental compounds and organic chemistry to examine the matter of reasoning and conversion, which is the college entrance examination exam questions over the years, but this year are highlighted by the calculation of quantitative inferences, reflecting the chemical changes not only have a qualitative relationship between the material conversion, but also exist quantitative reaction Relationship characteristics of this discipline. Focus on the chemical experiment examines the basic
