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...

find enthalpy change
3. When 2.617 g of AX (s) dissolves in 141.2 g of water in a coffee-cup calorimeter the temperature rises from 24.5 °C to 36.5 °C. Calculate the enthalpy change (in kJ/mol) for the solution process. AX(s) - A+ (aq) + X(aq) Assumptions for this calculation: The specific heat of the solution is the same as that of pure water (4.18 J/gK) The density of water = 1.000 g/mL. The liquid's final volume is not changed by...
