How much heat is absorbed/released when 30.00 g of NH3(g) react in the presence of excess  (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)H = 1168 kJ

A) 514.4 kJ of heat are absorbed.
B) 514.4 kJ of heat are released.
C) 2057 kJ of heat are absorbed.
D) 2057 kJ of heat are released.
