Ignition wires heat sample Thermometer Stirrer A bomb calorimeter, or constant volume calorimeter, is a device often used to determine the heat of combustion of fuels and the energy content of foods. Since the "bomb" itself can absorb energy, a separate experiment is needed to determine the heat capacity of the calorimeter This is known as calibrating the calorimeter In the laboratory a student burns a 0.319-g sample of phenanthrene (C14H10 in a bomb calorimeter containing 1070. g of water....

A 0.539-g sample of quinizarin (C14H8O4) is burned in a bomb calorimeter and the temperature increases from 24.70 °C to 27.00 °C. The calorimeter contains 1.19×103 g of water and the bomb has a heat capacity of 912 J/°C. Based on this experiment, calculate ΔE for the combustion reaction per mole of quinizarin burned (kJ/mol). C14H8O4(s) + 14 O2(g) 14 CO2(g) + 4 H2O(l) E = kJ/mol

A 1.720 g sample of naphthalene (formula C10H8) reacts completely in a bomb calorimeter containing 500 g of water. The temperature of the water and the bomb calorimeter increased from 24.00 degrees C to 47.57 degrees C. The heat capacity of the empty calorimeter is 850.0 J/degrees C. The specific heat capacity of water is 4.18 J/g(degrees C). Determine the enthalpy of combustion of naphthalene in units of kJ/mol.

A 1.764-g sample of heptanoic acid, C7H14O2 (130.19 g/mol) was burned in a bomb calorimeter with excess oxygen. The temperature of the calorimeter and the water before combustion was 23.68 °C; after combustion the calorimeter and the water had a temperature of 32.12 °C. The calorimeter had a heat capacity of 500 J/K, and contained 1.462 kg of water. Use these data to calculate the molar heat of combustion (in kJ) of heptanoic acid.
