Ignition wires heat Thermometer Stirrer A bomb calorimeter, or a constant volume calorimeter, is a device often used to determine the heat of combustion of sample fuels and the energy content of foods. In an experiment, a 0.5650 g sample of quinizarin (C14H804) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.187×103 g of water. During the combustion the temperature increases from 23.98 to Water 26.55 °C. The heat capacity of water is 4.184 J gloC1. The heat capacity of the calorimeter was determined in a previous experiment to be 770.8 J/°C. Assuming that no energy is lost to the surroundings, calculate the molar heat of combustion of quinizarin based on these data. C14H804(s) + 1402(g) → 4 H20(1) + 14 CO2(g) + Energy Sample dish Burning sample Steel bomb Insulated outside chamber Molar Heat of…
