In the (Bomb Calorimetry) experiment, 1.10 g of anthracene (C14H10) was burned in a constant volume bomb calorimeter. The temperature of water rose from 20.28 °C to 24.05 °C. If the heat capacity of the bomb plus water was 10.17 kJ/°C: In the (Bomb Calorimetry) experiment, 1.10 g of anthracene (C14H10) was burned in a constant volume bomb calorimeter. The temperature of water rose from 20.28 °C to 24.05 °C. If the heat capacity of the bomb plus water was 10.17 kJ/°C:
-Calculate Δc.mH at 25°C
-Why excess oxygen was used in this experiment? Why not using ambient air?
