Question 1

Find ΔH°rxn for the reaction
         2Ag2S(s) + 2H2O(l) → 4Ag(s) +  2H2S(g) + O2(g).
         [ΔH°f (Ag2S(s)) = –32.6 kJ/mol; ΔH°f (H2S(g)) = –20.5 kJ/mol; ΔH°f (H2O(l)) = –285.5 kJ/mol]


Question 2

Find ΔH°rxn for the reaction
         2Na(s) + 2H2O(l) → 2NaOH(aq) + 2H2(g).
         [ΔH°f (NaOH(aq)) = –426.8 kJ/mol; ΔH°f (H2O(l)) = –285.5 kJ/mol]
