Show all of your work! 1. What mass of benzene must be formed from its elements, in a bomb calorimeter that has a heat capacity of 6.57 kJ/C, to lower the temperature from 27.5°C to 12.2°C? [3 marks] Different cells use different enzymes to metabolize glucose, C,H,O,(aq), in the absence of oxygen. Muscle cells will convert glucose to lactic acid, C,H,O,(aq), as represented by the following equation. Use the following information to answer the next 3 questions. C₂H₂O(aq) muscle cellentyme, 2C,H,O,(aq) + 125.713 Yeast cells will convert glucose to ethanol, C,H,OH(aq), and carbon dioxide, CO₂(g), as represented by the following equation. CHO(g) yallazyme, 2C,H,OH(aq) + 2C0,(g) + 79.9 kJ A student dissolved 6.50 g of glucose into each of two identical polystyrene calorimeters containing 1000 ml of water. She then added muscle cell enzymes to the contents of one calorimeter and yeast cell enzymes to the contents of the other, covered the calorimeters, and monitored the temperature change in each. 2. The calorimeter that would have the greatest change in temperature would be the one containing enzymes from i cells. The manipulated variable in this experiment is the i added to the contents of each calorimeter. The statements above are completed by the information in row Row A. B. C. D. 1 muscle muscle yeast yeast ii mass of glucose type of enzyme mass of glucose type of enzyme
