Chemistry Pre lab experiment 19
EXPERIMENT 19 Pre-Laboratory Questions 1. 25.000 grams of water at 45 ec was added to 2500 grams of water at 2030 C in a coffee cup calorimeter. Upon mixing, the equilibrium temperature attained by the system was specific heat of water is 4.184 /g C. What is the calorimeter constant for the coffee cup calorimeter? 2. 25.00 mLof 1.000 M HCl is mixed with 25.00 mL of 1.00 M LioH in the calorimeter (same calorimeter from Question 1). The initial temperature of the HC1 and LioH solutions is 20.50 eC, and the equilibrium temperature of the reaction mixture is 3850 C. Assume the density and the specific heat of the solution is the same as for water, 1.00 g/mL and 4.184 C, respectively. a. Determine q solution Cheat absorbed or released by the reaction mixture)? 255
