A refrigerator contains approximately 17cubic feet, or about 480 liters, of air. Assuming it acts as an ideal gas with a molar CV of 12.47 J/mol.K, what is the change in U in cooling the air from normal room temperature 22C to refrigerator temperature 4C? Assume an initial pressure of 1.00 atm.

Calculate H when a 38-g sample of glucose, C6H12O6(s), burns in excess O2(g) to form CO2(g) and H2O() in a reaction at constant pressure and 298.15 K.

Carbon monoxide poisoning results when carbon monoxide replaces oxygen bound to hemoglobin. The oxygenated form of hemoglobin, HbO2 carries O2 to the lungs.
