Because on one side you have two hydrogens and two oxygens and on the other side of the equation you have two hydrogens and only one oxygen.
Zn + CuSO4 -> ZnSO4 + Cu
The chemical equation is 2Na + H2SO4 --> Na2SO4 + H2
its already balanced

Me too i don't know
2H2 + O2 --> 2H2O
This is a balanced chemical equation.
Zn + CuSO4 -> ZnSO4 + Cu
Cl2(g) + 2KI --> 2KCl(aq) + I2(s)
The chemical equation is 2Na + H2SO4 --> Na2SO4 + H2
its already balanced
iron :)
2Al + N2 ----> 2AlN
2
No. It would have to be H2O2 - H2 = O2 in order to be balanced.
