Write a balanced equation for the combustion of C5H12(l)(pentane)

-- i.e. its reaction with O2(g)forming the products CO2(g)and H2O(l).

Given the following standard heats of formation:

• ΔHf°of CO2(g)is -393.5 kJ/mol
• ΔHf°of H2O(l)is -286 kJ/mol
• ΔHf°of C5H12(l)is -146.4 kJ/mol

What is thestandard heat of reaction(ΔH°) for the combustion reaction of C5H12(l)?

-3537.1 kJ  ( i got this one)

Calculate the difference, ΔH-ΔE=Δ(PV) for the combustion reaction of 1 mole of pentane. (Assume standard state conditions and 298 K for all reactants and products.)
