Butane c4h10 ( = –125.7), combusts in the presence of oxygen to form co2 (g) (hf = –393.5 kj/mol), and h2o(g) (hf = –241.82) in the reaction:
2c4h10 (g) + 13o2 (g) = 8co2 (g) + 10h2o (g)
what is the enthalpy of combustion, per mole, of butane? (a) -2,657.5 kj/mol(b) -5315.0 kj/mol(c) -509.7 kj/mol(d) -254.8 kj/mol
