Quinine 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 (c6h4o2) is burned in a bomb calorimeter with a heat capacity of 1.56kj/c. the temperature of the calorimeter increases by 3.2 degrees c. calculate the energy of combustion of quinone per gram and per mole.

Achemical equilibrium between gaseous reactants and products is shown. n2(g) + 3h2(g) ⇌ 2nh3(g) how will the reaction be affected if the pressure on the system is increased? it will shift toward the reactant side as there is lower pressure on the reactant side. it will shift toward the product side as there is higher pressure on the product side. it will shift toward the reactant side as there are a greater number of moles of gas on the reactant side. it will shift toward the product side as there are a fewer number of moles of gas on the product side.
