Natural gas is typically about 95% methane. The other 5% is a complex mixture of other hydrocarbons (percent by mass). Let’s assume the 5% is all ethane, C2H6. Balance and calculate the heat of combustion of ethane, ∆Hcomb (kJ/mole), using reaction below.
C2H6 (g) + O2 (g) → CO2 (g) + H2O (g)

A mixture of methane gas, CH4(g), and pentane gas, C5H12(g), has a pressure of 0.5427 atm when placed in a sealed container. The complete combustion of the mixture to carbon dioxide gas, CO2(g), and water vapor, H2O(g), was achieved by adding exactly enough oxygen gas, O2(g), to the container. The pressure of the product mixture in the sealed container is 2.417 atm. Calculate the mole fraction of methane in the initial mixture assuming the temperature and volume remain constant.
