can anyone help with balacing equations for the stoichiometric coefficients?

Question

48 KNO3+ _ C 12 H22O11 ? CO2+ _ N2+ _ K2CO3+ _ H2O
or
6 KNO3+ _ S + ? H2O _ H2SO4+ _ N2+ _ K2SO4
or
5 S + _ KNO3 + _ H2O _ H2 SO4 + ? N2 + _ K2SO4
or
5 C12H22O11 + ? KNO3 _ CO2 + _ N2 + _ K2CO3 + _ H2O

Answer 1

12KNO3 + C12H22O11 -> 6CO2 + 6N2 + 6K2CO3 + 11H2O

5S + 6KNO3 + 2H2O -> 3N2 + 3K2SO4 + 2H2SO4

The last one is the sum of the above two eqns.
