Transcribed Image Text: 9) a) A 2.200-g sample of quinone (C,H4O2) is burned in a bomb calorimeter whose total heat capacity is 7.854 kJ/°C. The temperature of the calorimeter increases from 23.44°C to 30.57°C. What is the heat of combustion per gram of quinone? Per mole of quinone?

A 2.200-g of quinone, C6H4O2, is burned in a bomb calorimeter whose total heat capacity is 7.854 KJ/°C. The temperature of the calorimeter increased from 23.44°C to 30.57°C. What is the heat of combustion per gram of quinone?

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.

The complete combustion of salicylic acid releases 21.90 kJ of energy per gram of salicylic acid.In a particular bomb calorimeter (initially at room temperature), the combustion of 0.2745 g of salicylic acid, in the presence of excess oxygen, causes the temperature of the calorimeter to rise by 1.85 °C.When a 0.2999-g sample of an unknown organic …

Solution for Some beetles defend themselves by spraying hot quinone, C6H4O2(l), at their enemies. Calculate H° (in kJ/mol) for this reaction.

The following data is for the oxidation of catechol (the substrate) to o-quinone by the enzyme o-diphenyl oxidase. Additional data is also provided for when the reaction is run in the presence of p-hydroxybenzoic acid (PBHA). All data was acquired by …

Solution for 1. Calculate the heat evolved when 13.56g of oxygen gas (O2) is used to burn white phosphorus at standard temperature and pressure according to…
