A buffer solution is prepared by adding NaH2PO4 to a solution of H3PO4 (phosphoric acid).
H3PO4(aq) = H+ (aq) + H2PO4 (aq)

Consider the following reactions. (note: (s) = solid, (l) = liquid, and (g) = gas.) mg(s) + ½o2(g) → mgo(s) + 146 kcal/mole h2(g) + ½o2(g) → h2o(g), δh = -57.82 kcal/mole what type of reaction is represented by the previous two examples?
