Challenge Problems
Push your limits with challenges.
Question 1
A 0.500 g sample of glucose (C₆H₁₂O₆) is burned in a bomb calorimeter. If the calorimeter absorbs 15,000 J of heat and the temperature rises by 4 K, calculate ΔH for the combustion.
💡 Hint: Count the moles of gaseous products and reactants during combustion.
Question 2
Using Hess's Law, determine ΔH when the total reaction involves converting ethane (C₂H₆) to carbon dioxide (CO₂) and water (H₂O), given ΔH_f° values.
💡 Hint: Recollect previous examples of using enthalpy of formation in your calculations.
