Please answer question 8 part A
![**Educational Content: Combustion of Naphthalene**
Mothballs are composed primarily of the hydrocarbon naphthalene (\(C_{10}H_8\)). When 1.025 g of naphthalene is burned in a bomb calorimeter, the temperature rises from 24.25 °C to 32.33 °C.
### Part A
**Objective:**
Find \(\Delta E_{\text{rxn}}\) for the combustion of naphthalene. The heat capacity of the calorimeter, determined in a separate experiment, is 5.11 kJ/°C.
**Instructions:**
Express the change in energy in kilojoules per mole to three significant figures.
**Input Section:**
\(\Delta E_{\text{rxn}} = \boxed{\phantom{0000}}\) kJ/mol
This section involves solving for the energy change using the given data and placing the final answer in the designated box. Use the formula:
\[
\Delta E_{\text{rxn}} = -C \times \Delta T
\]
Where \(C\) is the heat capacity of the calorimeter, and \(\Delta T\) is the change in temperature. Ensure your final answer is adjusted for moles of naphthalene and rounded to three significant figures.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fded90a0e-1aa2-42d3-8902-387fb21746ad%2Fdd592160-6d7a-4ee5-9fcb-ce5d0794909a%2F5tbncbh_processed.png&w=3840&q=75)
