Challenge Problems
Push your limits with challenges.
Question 1
You conduct an experiment mixing 100 mL of 0.50 M HCl and 100 mL of 0.50 M NaOH, measuring a temperature rise from 25.0 °C to 37.0 °C. Calculate the enthalpy change per mole of water produced, given the specific heat capacity remains as 4.18 J/(g·°C).
💡 Hint: Calculate moles first to find accurate ΔH.
Question 2
In a calibration experiment, you determine that your coffee-cup calorimeter has a heat capacity of 50 J/°C. A reaction causes the temperature of the calorimeter to increase by 5°C. How much heat did the calorimeter absorb?
💡 Hint: Think about how to calculate total heat absorbed.
