When in danger, bombardier beetles can fire a hot, toxic mixture of chemicals at their attacker. This
mixture contains quinone, C6H4O2, a compound that is formed by the reaction of hydroquinone, CH4(OH)2,
with hydrogen peroxide, H2O2. The equation for the overall reaction is:
CH4(OH)2(aq) + H2O2(aq) → C6H4O2(aq) + 2H2O(ℓ)
Use the following data to calculate the enthalpy change, in kJ mol-1
, for the above reaction.
