20 kg of LiCl(s) is added to 125 kg of an aqueous solution containing 10 wt% LiCl at 25 °C? If the mixing process is isothermal, how much heat must be removed from the system? The molecular weights are 42.39 g/mol for LiCl and 18.015 g/mol for water. The heat of solution for 1 mole of LiCl in 8.145 moles water is about -32 kJ/mole LiCl(s). The heat of solution for 1 mole of LiCl in 21.177 moles water is about -35 kJ/mole LiCl(s).

13. calculate the initial concentration (before precipitation) of carbonate ions after the addition of each 0.05 ml of solution b to the 1.00 l beaker of solution a. divide the work among group members and write the answers in the table in model 3. assume the volume change as solution b is added is negligible. 14. notice the initial concentrations of zn2+ - and cu2+ in the table in model 3. a. explain how these were obtained from the data in model 2. b. as solution b is added and precipitates form, do these initial concentrations change? 15. use the data in model 2 to indicate the presence of precipitate (either znco3 or cuco3) after each 0.05 ml addition of solution b in model 3. 16. use the initial concentrations of carbonate ions and zinc ions to calculate the reaction quotient, qsp for the zinc carbonate scenarios in model 3. divide the work among group members and write the answers in the table in model 3. 17. use the initial concentrations of carbonate ion and copper(ii) ions to calculate the qsp for the copper(ii) carbonate scenarios in model 3. divide the work among group members and write the answers in the table in model 3.
