Balance this equation ( I )H2O2+Mno2=H2O+O2

Open in App

Solution

MnO2 + 2H2O2 --> MnO2 + O2 + 2H2O
No reaction takes place between H2O2 and MnO2, but MnO2 is used in the preparation of Oxygen in laboratories.

Hydrogen peroxide (H2O2) decomposes very slowly. But in presence of manganese dioxide (MnO2), the reaction speeds up.
