Using ΔH°f values found in Appendix D, calculate (a) the
standard enthalpy change for the dissolution of AlCl3(s) in water,
then (b) calculate the final temperature of the solution when 2.50
g of AlCl3(s) is dissolved in 52.50 g of water at 20.0°C. Use 4.18
J/g°C for the specific heat of the solution. Remember to write a
complete BALANCED reaction.

Appendix D: AlCl3(s) = -705.6 kJ/mol
