Question

the References to important values i eded for the question Ignition Thermometer Stirrer sample A bomb calorimeter, or a constant volume calorimeter, is a device often used to determine the heat of combustion of fuels and the energy content of food In an experiment, a 0.5230 g sample of 1-naphthale acid (C,H,O,) is burned completely in a bomb calorimeter. The calorimeter is surrounde of water. During the combustion the temperature increases from 22.13 to 24.81°C. The heat capacity of water is 4.184 Jgcl Water The heat capacity of the calorimeter was determined in a previous experiment to be 951.6 Assuming that no energy is lost to the surroundings, calculate the molar heat of combustion of 1-naphthoic acid based on these data C1,0() +120,($) — 4H,0) + 11 CO2() + Energy Molar Heat of Combustion - Ilmol Insulated outside chamber Sample dish Burning sample Combustion (bomb) calorimeter.
