三是传统考试的重点,讲了化学反应中的电子转移和能量变化。Changes in matter involve the rearrangement and/or reorganization of atoms and/or the transfer of electrons.
四是抽象知识的难点,讲了化学反应的机理和化学反应速率。
Rates of chemical reactions are determined by details of the molecular collisions.
五是承上启下的关键,讲了物质能量的变化和热力学原理。
The laws of thermodynamics describe the essential role of energy andexplain and predict the direction of changes in matter.
六是计算考察的必考,讲了化学平衡以及相关能量变化。
Any bond or intermolecular attraction that can be formed can be broken.These two processes are in a dynamic competition, sensitive to initialconditions and external perturbations.
不难看出,改革后的AP化学更加注重图像问题,希望学生能用微观粒子描述物质的性质,反应和变化
总之不管题型如何改变,所考的化学知识仍是教材上的内容,大家平时不仅要学好基础知识,更要懂得融会贯通,举一反三,这样即便题目再变,也能从容应对!
