Solution

I) Here Mg+O2=MgO is not balanced,here the two oxygen are in left side but in right side only one.

balanced equation
2Mg+O2=2MgO

II) N2+3H2=2NH3
Is balanced equal number of elements in both the sides

III)
H2O2=H2O+O2
It is not balanced because oxygen are not balanced
Balanced equation is
2H2O2=2H2O+O2
