What is the change in enthalpy for the combustion reaction of butane, C4H10?

2C4H10 (g) + 13O2 (g) → 10H2O (g) + 8CO2 (g)

Given:

C4H10 (g) : ΔHf ° = - 125 kJ

H2O (g) : ΔHf ° = - 242 kJ

CO2 (g) : ΔHf ° = - 393.5 kJ

The formulas for ethane, ethene, and ethyne are C 2 H 6 C2H6, C 2 H 4 C2H4, and C 2 H 2 C2H2, respectively. Rank these compounds by the length of the carbon-carbon bond.
