Title: How much heat is absorbed/released when 10.00 g of NH3(g) reacts in the presence of excess O2(g) to Post by: Whelan on May 6, 2015 How much heat is absorbed/released when 10.00 g of NH3(g) reacts in the presence of excess O2(g) to produce NO(g) and H2O(l) according to the following chemical equation?
4 NH3(g) + 5 O2(g) → 4 NO(g) + 6 H2O(l) ΔH° = +1168 kJ A) 171.5 kJ of heat are absorbed. B) 171.5 kJ of heat are released. C) 686.0 kJ of heat are absorbed. D) 686.0 kJ of heat are released.
