Compare the heat evolved at constant pressure per mole of oxygen in the combustion of sucrose (C₁₂H₂₂O₁₁) and palmitic acid (C₁₆H₃₂O₂) with the combustion of a typical protein, for which the empirical formula is C_4.3H_6.6NO. Assume for the protein that the combustion yields N₂(g), CO₂(g), and H₂O(l). Assume that the enthalpies for combustion of sucrose, palmitic acid, and a typical protein are 5647 kJ mol^–1, 10,035 kJ mol^–1, and 22.0 kJ g⁻¹, respectively. Based on these calculations, determine the average heat evolved per mole of oxygen consumed, assuming combustion of equal moles of sucrose, palmitic acid, and protein.
