补充资料：化学反应方程式配平法
（一）最小公倍数法
这种方法适合常见的难度不大的化学方程式。例如，kclo3→kcl+o2↑在这个反应式中右边氧原子个数为2，左边是3，则最小公倍数为6，因此kclo3前系数应配2，o2前配3，式子变为：2kclo3→kcl+3o2↑，由于左边钾原子和氯原子数变为2个，则kcl前应配系数2，短线改为等号，标明条件即：
2kclo32kcl+3o2↑
（二）奇偶配平法
这种方法适用于化学方程式两边某一元素多次出现，并且两边的该元素原子总数有一奇一偶，例如：c2h2+o2──co2+h2o，此方程式配平从先出现次数最多的氧原子配起。o2内有2个氧原子，无论化学式前系数为几，氧原子总数应为偶数。故右边h2o的系数应配2（若推出其它的分子系数出现分数则可配4），由此推知c2h2前2，式子变为：2c2h2+o2==co2+2h2o，由此可知co2前系数应为4，最后配单质o2为5，写明条件即可：
2c2h2+5o24co2+2h2o
（三）观察法配平
有时方程式中会出现一种化学式比较复杂的物质，我们可通过这个复杂的分子去推其他化学式的系数，例如：fe+h2o──fe3o4+h2，fe3o4化学式较复杂，显然，fe3o4中fe来源于单质fe，o来自于h2o，则fe前配3，h2o前配4，则式子为：3fe+4h2o＝fe3o4+h2↑由此推出h2系数为4，写明条件，短线改为等号即可：
3fe+4h2ofe3o4+4h2↑
