Let's try this:
MnO2 + H2O2 --->
This is a classic demo. Look up the catalytic decomposition of hydrogen peroxide.
In other words:
2H2O2 + MnO2 ---> 2H2O + MnO2 + O2
The MnO2 is not actually consumed in the reaction since it is the catalyst. Usually, the MnO2 is written above the arrow, but I can't do that here. Here's an image showing what I mean:

There is no reaction between MnO2 and H2O.
(MnO2 and H2O2 react, but that is not what this question asked about.)
