A quantity of 200.0 mL of 0.862 M HCl is mixed with 200.0 mL of 0.431 M Ba(OH)2 in a coffee-cup calorimeter (Hint: write and balance the chemical equation for this neutralization process). The initial temperature of HCl and Ba(OH)2 is the same at 20.48 ºC. The final temperature of the reaction mixture is 26.30 ºC. Assume the specific heat of the solution is the same as that of water and the density of the solution is 1.00 g/mL. Calculate the heat of neutralization (i.e., ?Hreaction per mole) for the process
H+ (aq) + OH- (aq) à H2O (l)
