The sugar arabinose, C5H10O5, is burned completely in oxygen in a calorimeter. C5H10O5(s) + 5O2(g) 5CO2(g)
Question:
C5H10O5(s) + 5O2(g) → 5CO2(g) + 5H2O(l)
Burning a 0.548-g sample caused the temperature to rise from 20.00oC to 20.54oC. The heat capacity of the calorimeter and its contents is 15.8 kJ/oC. Calculate ∆H for the combustion reaction per mole of arabinose.
