Challenge Problems
Push your limits with challenges.
Question 1
A bomb calorimeter has a heat capacity of 5000 J/°C. If the temperature rises from 25.0 °C to 35.0 °C after burning 1.5 g of a hydrocarbon, determine the energy released during combustion.
💡 Hint: Focus on calculating the temperature change before applying the formula.
Question 2
A sample of a fuel results in a temperature increase of 3.5 °C in a bomb calorimeter with a heat capacity of 7500 J/°C. If the number of moles of gas decreases during combustion, explain how you would compute the enthalpy change considering Δ(n_gas).
💡 Hint: Clarify how to incorporate gas losses into the calculation for ΔH.
