Unformatted text preview: the energy in one serving of Italian sausage (in kJ and kcal). Experiments: 1) 1.392 g benzoic acid (q rxn = -26.43 kJ/g), T = 18.27 o C 2) 1.526 g fats, T = 28.87 o C 3) 3.917 g proteins, T = 33.06 o C 4) 2.161 g carbohydrates, T = 18.24 o C Name: 2 Part II: Phase Change. II.1 (13 points) Adding a 40 g ice cube at 15 o C to a cup containing 200 mL coffee (liquid water) at 95 o C lowers the temperature of the coffee to 65 o C. Calculate q fusion for water in kJ/mol. Useful constants: specific heat capacity for liquid water is 4.184 J/g o C and for solid water is 1.84 J/g o C....
