Compare the heat evolved at constant pressure per mol oxygen in the combustion of sucrose (C12H22O11) and palmitic acid (C16H32O2) with the combustion of a typical protein, for which the empirical formula is C4.3H6.6NO. Assume for the protein that combustion yields N2 (g), CO2 (g) and H2O (l). Assume that enthalpies for combustion of sucrose, palmitic acid, and a typical protein are 5647 kJmol-1, 10,035 kJ mol-1, and 22.0 kJ g-1, respectively. Based on these calculations, determine the average heat evolved per mol of oxygen consumed, assuming combustion of equal mols of sucrose, palmitic acid, and protein.

13. calculate the initial concentration (before precipitation) of carbonate ions after the addition of each 0.05 ml of solution b to the 1.00 l beaker of solution a. divide the work among group members and write the answers in the table in model 3. assume the volume change as solution b is added is negligible. 14. notice the initial concentrations of zn2+ - and cu2+ in the table in model 3. a. explain how these were obtained from the data in model 2. b. as solution b is added and precipitates form, do these initial concentrations change? 15. use the data in model 2 to indicate the presence of precipitate (either znco3 or cuco3) after each 0.05 ml addition of solution b in model 3. 16. use the initial concentrations of carbonate ions and zinc ions to calculate the reaction quotient, qsp for the zinc carbonate scenarios in model 3. divide the work among group members and write the answers in the table in model 3. 17. use the initial concentrations of carbonate ion and copper(ii) ions to calculate the qsp for the copper(ii) carbonate scenarios in model 3. divide the work among group members and write the answers in the table in model 3.
