High-purity benzoic acid (C6H5COOH; ΔHrxn for combustion = −3227 kJ/mol) is used as a standard for calibrating bomb calorimeters. A 1.221-g sample burns in a calorimeter (heat capacity = 1365 J/°C) that contains exactly 1.350 kg of water. What temperature change is observed? C?
Benzoic acid, C7H6O2, occurs naturally in many berries. A 1.50-g sample of benzoic acid is combusted in a bomb calorimeter. The temperature of the calorimeter increases from 22.50 0C to 31.69 0C. The calorimeter contains 775 g water and has a heat capacity of 893 J/0C. Based on this information, how much energy (in kJ) is released when you metabolize 1.50 g of benzoic acid? The specific heat capacity of water is 4.184 J/(g⋅0C).

3. The enthalpy of combustion of benzoic acid is 3227 kJ/mole and the molecular mass is 122 g/mole. How much heat is generated when 1.00 g of benzoic is combusted? If this heat were directed totally into 500 mL of water, what temperature change would be observed?
benzoic acid was combusted in a bomb calorimeter resulting in a 2.3 degree C incresse Consider the following experiment performed by students in the Physical Chemistry class last semester: Benzoic acid, C6H602, was combusted in a bomb calorimeter, resulting in a 2.3°C increase in temperature of the calorimeter (part of the surroundings). 2 C.H.O2 (s) + 15 O2(g) 12 CO2(g) + 6H20 (1) A. Based on the reaction above and described observations, indicate the sign of the thermodynamic changes for...
Under constant-volume conditions the heat of combustion of benzoic acid (C6H5COOH) is 26.38 kJ/g. A 2.740?g sample of benzoic acid is burned in a bomb calorimeter.
