化学平衡是高考考查的重点,也是平时教学的难点,还是学生的失分点,现将化学平衡题的几种思维方法总结如下。一、平衡模式思维法(或三段思维法)化学平衡计算中,依据化学方程式列出“起始”、“变化”、“平衡”时各物质的量(或体积、或浓度),然后根据已知条件建立代数等式进行解题的一种方法。 Chemical balance is the focus of the college entrance examination, but also the difficulty of teaching in peacetime, or the student’s point of failure, and now summarizes several ways of thinking about chemical balance. 1. Balanced mode thinking (or three-phase thinking) In the chemical balance calculation, the amount (or volume) of each substance is listed according to the chemical equations of “start”, “change”, and “balance”. Or concentration), and then establish an algebraic equation based on known conditions to solve the problem.
