Question 1

When 1.820 g of anthracene, C14H10, is combusted in a bomb calorimeter that has a water jacket containing 500.0 g of water, the temperature of the water increases by 34.52°C. Assuming that the specific heat of water is 4.18 J/(g ∙ °C), and that the heat absorption by the calorimeter is negligible, estimate the enthalpy of combustion per mole of anthracene.
◦ -7070 kJ/mol
◦ -39.7 kJ/mol
◦ +39.7 kJ/mol
◦ -8120 kJ/mol

Question 2

◦ ethylene glycol
◦ gold
◦ air
◦ methanol
