Consider the dissolution of a 1.5g of salt XY in 75mL of waterwithin a calorimeter. The temperature of the water decreasedby .93C. The heat capacity of the calorimeter is42.2J/C. The density of the water (and the solution) is1.00g/mL. The specific heat of the solution is4.184J/gC
a). Identify the system; write a reaction that describesthe event occuring in the system
b). Which of the following best describes thesurroundings. Explain.-the water alone-the solution alone (dissolved salt and water)-water plus the calorimeter-the calorimeter plus solution
c) Determine if the reaction was endothermic or exothermic. Explain
d) Determine the quantity of heat gained or lost by thesurroundings. Keep in mind your answers to item b and cabove.
e) Determine the enthalpy change, for dissolving thesalt. Report the value as the total energy absorbed orreleased when the entire sample of salt dissolves and then on apergram basis. What additional information would be needed toreport the enthalpy change on a per mole basis?
