Chapter 9, Problem 9.71(choose chapter or problem)
The bombardier beetle uses an explosive discharge as a defensive measure. The chemical reaction involved is the oxidation of hydroquinone by hydrogen peroxide to produce quinone and water: C6H4(OH)2(aq) 1 H2O2(aq) 88n C6H4O2(aq) 1 2H2O(l) Calculate DH for this reaction from the following data: C6H4(OH)2(aq) 88n C6H4O2(aq) 1 H2(g) DH 5 177.4 kJ H2(g) 1 O2(g) 88n H2O2(aq) DH 5 2191.2 kJ H2(g) 1 1 2O2(g) 88n H2O(g) DH 5 2241.8 kJ H2O(g) 88n H2O(l) DH 5 243.8 kJ
