2h2o2 → 2h2o + o2

The reaction is a decomposition reaction

When a single compound breaks down into two or more simpler products then the reaction is known as decomposition reaction. These reactions involve an energy source such as heat, light, or electricity that breaks apart the bonds of compounds. Decomposition reactions can be classified into three types: Thermal decomposition reaction. Electrolytic decomposition reaction. Photo decomposition reaction.

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."

i believe that it is a exoplanet
