Chapter 6, Problem 74E(choose chapter or problem)
Mothballs are composed primarily of the hydrocarbon naphthalene (C10H8). When 1.025 g of naphthalene burns in a bomb calorimeter, the temperature rises from 24.25 °C to 32.33 °C. Find rxn for the combustion of naphthalene. The heat capacity of the calorimeter, determined in a separate experiment, is 5.11 kJ/°C.

QUESTION:
Mothballs are composed primarily of the hydrocarbon naphthalene (C10H8). When 1.025 g of naphthalene burns in a bomb calorimeter, the temperature rises from 24.25 °C to 32.33 °C. Find rxn for the combustion of naphthalene. The heat capacity of the calorimeter, determined in a separate experiment, is 5.11 kJ/°C.
ANSWER:Solution 74E: tep 1 of 3 A sample of naphthalene is combusted in a bomb calorimeter. Heat (q) is transferred to a system by absorption which causes a change in temperature (T) of the system. The change in temperature is directly proportional to the heat transferred. Therefore, heat absorbed by the system is given by: q T (Or) q = CT where’C’ is the proportionality constant known as heat capacity of the system.
