This paper describes the decomposition reaction of potassium permanganate with hydrogen peroxide solution: hydrogen peroxide --- > water + oxygen 2h2o2 = = 2H2O + O2 to produce oxygen: potassium permanganate --- > potassium permanganate + manganese dioxide + oxygen decomposition reaction 2kmno4 = = k2mno4 + MnO2 + O2 charcoal combustion reaction in oxygen: charcoal + oxygen --- > carbon dioxide C + O2 = = CO2
