The enthalpy of the reaction H _(2 (g)) + 1/2 O _(2(g)) to H _(2) O _((g)) is Delta H _(1) and that of H _(2(g)) + 1/2 O _(2(g)) to H _(2) O _((l)) is Delta H _(2). Then

H_(2)SO_(4(aq)) + 2KOH_((aq)) rarr K_(2)SO_(4(aq)) + 2H_(2)O_((l)), Delta H for the above reaction is

C + HNO_(3)(aq) rarr NO_(2) + CO_(2) + H_(2)O(l) . Balance this equation.
