Chemistry

Assume 200. mL of 0.400 M HCl is mixed with 200 mL of 0.250 MBa(OH)2 in a constant-pressure calorimeter. The temperature of thesolutions before mixing was 25.10C; after mixng and alowing thereaction to occur, the temperature is 27.78C.Determine  ΔrH for this reaction in units ofkJ/mol-rxn.

2 HCl(aq) + Ba(OH)2(aq) -> BaCl2(aq) + 2 H2O(l)

The densities of all solutions are 1.00 g/mL
The specific heat capacitites of all solutions are 4.20 J/(gC)
