At constant volume, the heat of combustion of a particular compound, compound A, is −3294.0 kJ/mol. When 1.127 g of compound A (molar mass = 109.35 g/mol) is burned in a bomb calorimeter, the temperature of the calorimeter (including its contents) rose by 7.283 °C. What is the heat capacity (calorimeter constant) of the calorimeter? Suppose a 3.157- g sample of a second compound, compound B, is combusted in the same calorimeter, and the temperature rises from 23.23 °C to...

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 foods. In an experiment, a 0.3320 g sample of naphthalene (C10Hg) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.092x103 g of water. During the combustion the temperature increases from 22.54 to 25.04 °C. The heat capacity of water is 4.184 Jg=1°C-1 The heat capacity of the calorimeter was determined...

A bomb calorimetric experiment was run to determine the enthalpy of combustion of ethanol. The reaction is C2H5OH(l) + 3 O2(g) → 2 CO2(g) + 3 H2O(l) The bomb had a heat capacity of 500 J/K, and the calorimeter contained 610 g of water. Burning 4.50 g of ethanol, C2H5OH(L) resulted in a rise in temperature from 16.5 °C to 20.9 °C. Calculate the enthalpy of combustion of ethanol, in kJ/mol. (The specific heat capacity of liquid water is 4.184...
