Quinone is an important type of molecule that is involved in
Quinone is an important type of molecule that is involved in photosynthesis. The transport of electrons mediated by quinone in certain enzymes allows plants to take water, carbon dioxide, and the energy of sunlight to create glucose. A 0.1964-g sample of quinone (C 6 H 4 O 2 ) is burned in a bomb calorimeter with a heat capacity of 1.56 kJ/°C.

Quinone, which is used in the dye industry and in photography, is an organic compound containing only C, H, and O. What is the empirical formula of the compound if you find that 0.105 g of the compound gives 0.257 g of CO2 and 0.0350 g of H20 when burned completely? Given a molecular weight of approximately 108 g/mol, what is its molecular formula?

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: C 6 H 4 (OH) 2 ( aq ) + H 2 O 2 ( aq ) → C 6 H 4 O 2 ( aq ) + 2H 2 O( l ) Calculate Δ H for this reaction from the following data: C 6 H 4 (OH) 2 ( …
