QUESTIONS What would be the effect on your calculation of co if there was heat lost while transferring the shot? Explain why. 1. What would be the effect on your calculation of cow if the shot you heated was wet, and contained 2% water by weight when you poured it into the calorimeter? Explain why. 2. What would be the effect on your calculation of ccu if you didn't wait until the final mixture reached equilibrium temperature? Explain why. 3. What would be the effect on your calculation of ccu if you read the final equilibrium temperature too high? Explain why 4. 5. Is there any part of the apparatus we have not considered in the calculations? Problem: A mass (m) of aluminum at a temperature of 90.2'C is placed in a 32.5 g aluminum calorimeter containing 69.3 g of water. The water and the calorimeter are initially at a temperature of 14.5°C If the final equilibrium temperature of the mixture is measured as 75.5°C, determine the mass (m) of the aluminum. 122

    8. Suppose you and your lab partner each go to repeat the experiment. You take 4g of NaHCO3 and 4g of CaCl2 and dump them both simultaneously into your calorimeter that is filled with 400mL of water. Then you carefully measure the change in temperature. In a separate experiment, your partner first dissolves 4g of NaHCO3 into 200mL of water and then dissolves 4g of CaCl2 into a different 200mL of water. He then combines both solutions into an empty...

    In a physics lab students are conducting an experiment to learn about the heat capacity of different materials. The first group is instructed to add 1.5-g lead pellets at a temperature of 92°C to 125 g of water at 16°C. A second group is given the same number of 1.5-g pellets as the first group, but these are now aluminum pellets. Assume that no heat is lost to or gained from the surroundings for either group. (a) If the final...
