10) What is the enthalpy change of the reaction: 2NH3(g) + 4H₂O(1) 2NO₂(g) + 7H₂(g) Use the appendix for AHºf values A) 122.6kJ B) 1860kJ C) 1301.4 kJ D) 41.9kJ 11) Butane, C4H10(1), the fuel in many cigarette lighters, has a AH°f=-147.6 kJ/mol. Butane combustion produces CO2 (g) and H2O (g). Using enthalpies of formation, calculate the quantity of heat produced when 3.4 g of butane is completely combusted in air. C4H10+13/202-4CO2+ 5H20 A) +122.08kJ B)-464.7kJ C) -154.38kJ D) -1321.04kJ
