Manganese(IV) oxide was used as a catalyst during a reaction (stated below). Has the manganese(IV) oxide changed in any way after the reaction happened?
The reaction was hydrogen peroxide (H2O2) in the presence of manganese (IV) oxide (a catalyst). It was a decomposition reaction. So, the question is stated above, please answer it! :)

A catalyst is a material that changes the chemical rate of the reaction without itself being consumed in a reaction. Having said that, Manganese (IV) oxide is a catalyst that speeds up the decomposition of Hydrogen peroxide (H2O2) to water and Oxygen gas.
The balanced chemical equation for the decomposition of H2O2 can be written as:
2H2O2 -----> 2H2O + O2
Manganese (IV) oxide itself will not be affected in the reaction hence it will remain in the container as it is since it is not as well soluble in water.
Thanks you! Both very great answers!
- substances which alter the rate of reaction without undergoing any chemical change are called catalyst.
- catalysts which speed up reactions are called +ve catalyst.
- Hydrogen peroxide undergoes decomposition very slowlLY
- but in presence of manganese dioxide as a catalyst decomposition become very fast.
- 2H202------>2H2O + O2
- Manganese (IV) oxide itself will remain in the container.
