Calculate the standard enthalpy change for the precipitation reaction that takes place when 25.0 mL of 0.250 M barium chloride (BaCl2) and 50.0 mL of 0.100 M sodium sulfate (Na2SO4) react to form a precipitate of barium sulfate (BaSO4). The density of each solution is 1.00 g/mL and the specific heat capacity is 4.18 J/g°C. Assume a constant temperature of 25°C.
