balancing chemical equations pls...?

Question

C4 H10 + 02 -> CO2 + H2

C6 H12 06 + 02 -> CO2 + H2O

C3 H5 (NO3)3 -> CO2 + H2O + N2 + O2

NF3 + H20 -> HF + NO + NO2

CH3 OH + H2 -> CH4 +H2O

Answer 1

A. 2C4H10 + 13O2 --> 8CO2 + 10H2O (I assume you mean H2O, not H2 as a product. If you insist on H2 then: C4H10 + 4O2 --> 4CO2 + 5H2)

B. C6H12O6 + 6O2 --> 6CO2 + 6H2O

C. 2NF3 + 3H2O --> 6HF + NO + NO2

D. CH3OH + H2 --CH4 + H2O (it's already balanced)
