29. (4 points) Calculate A-H° for the combustion of ammonia, 4 NH3(g) + 7 O2(g) - 4 NO2(g) + 6 H₂O(l) using standard molar enthalpies of formation. molecule NH3(g) NO₂(g) H₂O(!) Name N₂(g) + O₂(g) → 2 NO(g) N₂(g) + 3 H₂(g) → 2 NH;(g) 2 H₂(g) + O₂(g) → 2 H₂O(g) AH (kJ/mol-rxn) -45.9 +33.1 -285.8 3=-298.6 -Hfinal-Hinitial 30. (4 points) Determine A.H° for the following reaction, 2 NH3(g) + 5/2 O₂(g) → 2 NO(g) + 3 H₂O(g) given the thermochemical equations below. Test # A.H=+180.8 kJ/mol-rxn AH-91.8 kJ/mol-rxn A.H=-483.6 kJ/mol-rxn 44 575.28
