纵观2007年高考化学试卷(含理科综合卷),有关“阿伏加德罗常数和阿伏加德罗定律”的试题仍是高考命题的热点。该类试题联系多、覆盖面广,涉及物质组成、结构、氧化还原反应、电化学等热点知识,主要考查物质的量、阿伏加德罗常数、摩尔质量、气体摩尔体积、物质的量浓度等概念的辨析与应用,以及与微观粒子(分子、原子、离子、电子、质子、中子等)之间的关系,较好地考查了思维的严密性。笔者结合2007年高考化学试题来谈谈有关“阿伏加德罗常数和阿伏加德罗定律”试题的解决方法。
Throughout the 2007 college entrance examination chemistry paper (including the science synthesis volume), questions on the “Avogadro’s constant and Avogadro’s law” are still hot topics of the college entrance examination proposition. This type of questions has many connections and covers a wide range of topics, including material composition, structure, redox reactions, electrochemical and other hot topics, mainly examining the amount of substances, Avogadro constant, molar mass, gas molar volume, substance concentration, etc. The analysis and application of concepts, as well as the relationship with microscopic particles (molecules, atoms, ions, electrons, protons, neutrons, etc.), have better examined the rigor of thinking. The author combines the 2007 college entrance examination chemistry test to talk about the “Avogadro constant and Avogadro’s law” test solution.
