Question:

A bomb calorimetry experiment is performed with xylose, C5H10O5(s), as the combustible substance.

The data obtained are

Mass of xylose burned: 1.183 g 

Heat capacity of calorimeter: 4.728 kJ/°C 

Initial calorimeter temperature: 23.29 °C 

Final calorimeter temperature: 27.19 °C

(a) What is the heat of combustion of xylose, in kilojoules per mole? 

(b) Write the chemical equation for the complete combustion of xylose, and represent the value of ΔrH in this equation. (Assume for this reaction that ΔU ≈ ΔrH.)
