How to balance the chemical equation: KMnO4-----K2MnO4+MnO2+O2 I don't understand. Please write down the balancing process step by step. Do n' t use the common method, don't use the "1" method. It's better to summarize the method after the matching. How to balance the chemical equation: KMnO4-----K2MnO4+MnO2+O2 I don't understand. Please write down the balancing process step by step.

1. Assuming that the coefficient of KMnO4 is 1, the coefficient of K2MnO4 K2MnO4 is 1/22 according to the conservation of K elements. According to the conservation of Mn elements, the Mn contained in KMnO4 is 1, and the Mn contained in 1/2 K2MnO4 is 1/2, so the Mn contained in MnO2 should be 1-1/2=1/2, so it can be known that the coefficient of MnO2 is 1/23. Finally,...
