　　ncluding common elements,nomenclature of ions and compounds, periodic trends inchemical and physical properties of the elements, reactivity of elements and prediction of products of chemical reactions, examples of simple organic compounds and compounds of environmental concern

　　会出10-11道题

　　SAT2化学备考书没有涉及的知识点：

　　1)lewis dot structure of a molecule

　　这是在巴郎和普林斯顿中都没有提到的SAT2化学知识点。

　　注意在这两本书中出现的是lewis dot structure of an atom，不要把二者混淆了啊，值得庆幸的是Kaplan SAT化学书中提到了，而且较为详细。

　　2)关于盐类的酸碱性问题

　　几乎所有关于SAT2化学备考书籍都没有说到，但是在普林斯顿的AP化学里acid and base salts有专门介绍，美国人分情况说的，简单总结成一句话：“谁强显谁性”，比如强酸弱碱盐，就是显弱酸性，强碱弱酸盐，就是显弱碱性。

　　3)关于实验仪器部分

　　巴郎写的都是实验仪器组装好的装置，而并非单个实验仪器的使用，此处过于跳跃了。

　　推荐普林斯顿里面的仪器部分，介绍每一种仪器的名称和用途，注意某些仪器在国内是没有的，或者少见的，大家要多注意。

　　以上就是新SAT2化学考试85道题的考点分布，希望对大家的SAT2化学考试有所帮助。
