$\bold {Rules\:for\:balancing \:equations:-}$ You have to add coefficients to the elements in such a way that the no. of atoms of each element is equal to that of those in the other side.

$\huge {Answers:-}$

1. MnO2 + 4Hcl = MnCl2 + 2H20 + Cl2

2. 4NH3 + 5O2 = 4NO + 6H20

3. 2C4H10 + 13O2 = 8CO2 + 10 H20

4. Fe2(SO4)3 + 3BaCl2 = 2FeCl3 + 3BaSO4

5. 3Cu+ 8HNO3= 3Cu(NO3)2 + 2NO +4H2O

6. 2KClO3 = 2 KClO2 + O2

7. 2Na + 2H20 = 2NaOH + H2

8. 2 ZnS + 3 O2 = 2 ZnO + 2 SO2

9. MgCl2 + 2 NaOH = Mg(OH)2 + 2 NaCl

10. 2NH4Cl + Ca(OH)2 = CaCl2 + 2 NH3 + 2 H2O

11. Al2O3 + 2 NaOH = 2 NaAlO2 + H2O

12. C2H5OH + 3 O2 = 2 CO2 + 3 H2O
