In a constant-pressure calorimetry experiment, 25.0 mL of 1.00 M HClO4 was mixed with 25.0 mL of 1.00 M LiOH in a calorimeter. Both solutions were initially at 21.5 OC. The final temperature of the mixture was 32.0OC. The heat capacity of the calorimeter is 30.1J/OC. The specific heat of the reaction mixture is 4.184 J/g°C and the density of all solutions is 1.00 g/mL. Calculate the qreaction. Report the numerical answer in kJ with correct significant digits (without units and not in scientific notation).
