__ NH3(g) + __ O2(g) --> __ NO(g) + __ H2O(g) Based on the enthalpies of formation, how much energy, in kJ, will be released when 4.50 grams of NH3(g) are reacted?

When hydrochloric acid reacts with potassium hydroxide solution, the following reaction occurs. hcl (aq) + koh (aq) h2o (l) + kcl (aq) the reaction gives off heat energy, so it is an reaction.
