摘要
介绍了一种新的化学反应方程式的配平方法,使用这种方法可以配平任何类型的氧化还原反应方程式,却不需知道反应式中氧化剂、还原剂氧化数的变化值及得失电子数。本方法包括下面几步:1)将要配平的反应式分解为2个半反应式,并将这2个半反应式通过添加氢原子配平;2)使用2个半反应式中氢原子数目的最小公倍数将2个半反应式相加,整理后便可得到最后的结果。
This paper introduces a new method of balancing chemical reaction equation.Using the method,you can balance any type of oxidation-reduction reaction equation,but it is not necessary to know the changing number of oxidation number and the number of electron gain or loss of oxidant and reductant in the chemical equation.This method includes the following steps:firstly,you must decompose the chemical equation to be balanced into two half equation,and balance into one equation with lowest common multiple of the number of hydrogens.After rearrangement,you can get the final result.
