Question

The bombardier beetle uses an explosive discharge as a ΔEfensive measure. The chemical reaction involved is the oxidation of hydroquinone by hydrogen peroxide to produce quinone and water:
C6H4(OH)2(aq) + H2O2(aq) → C6H4O2(aq) + 2H2O(l)
Calculate ΔH for this reaction from the following data:
C6H4(OH)2(aq) → C6H4O2(aq) + H2(g) ΔH = 177.4 kJ
H2(g) + O2(g) → H2O2(aq) ΔH = –191.2 kJ
H2(g) + ½ O2(g) → H2O(g) ΔH = –241.8 kJ
H2O(g) → H2O(l) ΔH = –43.8 kJ
