Reaction of manganes dioxide (MnO2) with hydrogen peroxide(H2O2)..
this reaction is catalytic decomposition of hydrogen peroxide in manganese dioxide this reaction produces oxygen gas O2 and H2O by generating heat (the reaction is exothermic). by adding soap in MnO2 and H2O2 produces elephant toothpaste as like in the reaction of KMnO4 and H2O2. #chemistryfun
