In the laboratory, a student burns a 0.340 g sample of anthracene (C14H10) in a bomb calorimeter containing 1120 g of water. The temperature increases from 25.80°C to 28.20°C. The heat capacity of water is 4.184 J/(g·°C). The molar heat of combustion is -7067 kJ per mole of anthracene.
C14H10 (s) + 33/2O2(g) → 14CO2 (g) + 5H2O(l) + Energy
