Answer:
A Reaction of decomposition is ocurred to hydrogen peroxide.
Explanation:
Hydrogen peroxide is a molecule that can break down into Hydrogen and Oxygen or decompose very slow under moderate temperature, as you can see in the image below, hydrogen peroxide has a high electronic cloud that makes it a great oxidizer.
Answer:
1) MgO + 2HBr -> MgBr2+H2O
2)2N2+5O2->2N2O5
3)C2H4+2O2->CO2+2H2O
4)Fe+2HCl->FeCl2+H2
