When 25.0 mL of 1.0 M H2SO4
is added to 50.0 mL of 1.0 M NaOH at 25.0 C in a calorimeter, the temperature of the aqueous solution
increases to 33.9 C. Assuming the specific heat of the solution is 4.18 J/(gC), that its density is 1.00 g/mL, and that the calorimeter itself absorbs a negligible amount of heat, calculate H (in kJ) for the reaction:
H2SO4(aq) + 2 NaOH (aq) 2 H2O (l) + Na2SO4
(aq)
