how much heat is absorbed/released when 25 .00g of NH3(g) reacts in the presence of excess O2 (g) to produce NO (g) andH2O (l) according to the following chemical equation?
4NH3(g) + 5O2 (g) ... 4NO (g) + 6H2O (l)

Considering the limiting reactant, what is the volume of NO gasproduced from 60.0 L of ammonia gas and 50.0 L of oxygen gas?(Assume constant conditions.)
4NH3(g) + 5O2(g) ---> 4NO(g) + 6H2O(g)

please include steps to solve, thanks!
