3. When 15.7 g of calcium chloride (CaClz) was dissolved in 200.0 ml of water in a coffee-cup calorimeter, the temperature of the solution increased from 25.00 °C to 34.13 °C, the dissolution of CaCl in water in units of kJ per mole of CaCl,. Calculate the entha lpy change(AH otn)for You can assume that the calorimeter loses only a negligible quantity of heat, that the total solution is 200.0 mL (adding the solid CaCl, did not change the volume...

4. In an experiment, when 23.6 of calcium chloride, CaCl2 were dissolved in water in a coffee- cup calorimeter (at constant pressure), the temperature rose from 25.0°C to 38.7°C. The dissolution process is: CaCiz(s) - Ca2+ (aq) + 2C1-(aq) The heat capacity of the solution and the calorimeter is 1258 J/°C. The molar mass of CaCl2 is 110.98 g/mol. 1) Determine the heat that was absorbed by the solution and calorimeter. (1 point) 2) Determine the heat that was released...
