a) Skeleton :CH4 + O2 --> CO2 + H2O

Balanced:CH4 +2 O2 --> CO2 +2 H2O

b) Skeleton :Na(s)+Cl2(g) → NaCl(s)

Balanced :2Na(s)+Cl2(g) → 2NaCl(s)

c) Skeleton :Fe+ O2 → Fe2O.

Balanced :4Fe+ 3O2 → 2Fe2O.

d) Skeleton :CuO - - >Cu(s) +O2(g)

Balanced :2CuO - - >2Cu(s) +O2(g)

e) Skeleton :Ca(s) +H2O→Ca(OH)2+H2

Balanced :Ca+2H2O→Ca(OH)2+H2
