A quantity of 2 x 102 mL of 0.862 Molar HCl is mixed with 2 x 102 mL
of 0.431Molar Ba(OH)2 in a constant pressure calorimeter that has a heat
capacity of 453 J/oC.
The initial temperature of the HCl and Ba(OH)2 solutions is the same
at 20.48oC. For the process
H+(aq) + OH-(aq) ( H2O(L)
the heat of neutralization is -56.2 KJ.
What is the final temperature of the mixed solution?
