To balance the chemical equations, the sum of each atom should be equal in both side of the arrow. Hence the answers can be written as;

2NaNO ₃ + PbO → Pb (NO ₃) ₂ + Na ₂ O

Ca ₃ P ₂ + 6H ₂ O → 3Ca (OH) ₂ + 2PH ₃

Fe ₂ O ₃ + 3CO → 2Fe + 3CO ₂

4NH ₃ + 7O ₂ → 4NO ₂ + 6H ₂ O

4FeS + 7O ₂ → 2Fe ₂ O ₃ + 4SO ₂

2C ₃ H ₆ O ₂ + 7O ₂ → 6CO ₂ + 6H ₂ O
