一、以阿伏加德罗常数(N_A)为载体,考查常见物质的状态、组成、结构和性质,常考常新这是选择题中的经典题型,仍旧受到新课程高考的推崇。阿伏加德罗常数是贯穿高中化学始终的物理量,是沟通微观世界和宏观世界的桥梁,这类题知识涵盖面大,不仅要求基本概念明确,而且要求审题细密,思维严密。如2010年广东理综卷第8题、2010年山东理综卷第9题、2010年福建理综卷第7题、2010年上海卷第7题、2010年江苏卷第5题、2010年四川理综卷第7题等。
First, to Avogadro’s constant (N_A) as a carrier, examining the state, composition, structure and nature of common substances, often test often new This is a classical multiple choice questions, still subject to the new curriculum respected college entrance examination. Avogadro’s constant is the physical quantity that runs through chemistry in high school. It is a bridge between the micro-world and the macro-world. Such knowledge covers a large area and requires not only clear basic concepts but also careful examinations and careful thinking. Such as the 2010 Guangdong rationale volume 8, Shandong Science Volume 9 in 2010, Fujian Science Volume 7 in 2010, the 2010 Shanghai Volume 7, 2010 Jiangsu Volume 5, 2010 Sichuan Rational comprehensive volume seventh questions and so on.
