Name: Chemistry 008, Spring 2008 Cornell University Dr. Pontrello Due 2/3/08 Learning Strategy Questions 1 Any time you write down a number, please include correct units when applicable. Clearly write any equation(s) that you are using to answer each question, and also clearly indicate the steps used to answer the questions, if appropriate. Part I: Meat Energy. I.1 (14 points) You read on a label of a package of Italian sausage that a serving size (100g) contains 13g fats, 3g carbohydrates, and 19g proteins. Using the following experimental data for combustion of the listed materials in a bomb calorimeter, calculate

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....
