A few chemical equations I need help balancing?

1. Si4H10 + O2 = SiO2 + 10H2O

2. NH3 + O2 = N2H4 + H2O

3. C12H26 + O2 = CO2 + H2O

Thanks in advance

2Si4H10 + 13O2 = 8SiO2 + 10H2O

Ammonia & Oxygen DOES NOT form Hydrazine (N2H4)
4NH3 + 302 = 2N2 + 6H20

2C12H26 + 37O2 =24CO2 + 26H2O

previous answerer has not balanced Si

1) 2 Si4H10+9 O2--->4 SiO2+10H2O

2) 2 NH3+ O2--->N2H4 +2 H2O

3)C12 H26 + 18.5O2 ---> 12CO2 +13 H2O
