When 25.0 mL of 1.0 M H2SO4 is added to 50.0 mL of 1.0M NaOH at 25 °C in a calorimeter, the temperature of the aqueous solution increases to 33.9 °C. Assuming that the specific heat of the solution is 4.18 J/g-°C, that the solution density is 1.00 g/mL, and that the calorimeter itself absorbs a negligible amount of heat, calculate AH (in kJ/mol) for the reaction. H2SO4 (aq) + 2 NaOH (aq) → 2 H2O (I) + NażSO4 (aq) -56 kJ/mol O -110 kJ/mol 110 kJ/mol 56 kJ/mol

Question 39 When 25.0 mL of 1.0 M H2SO4 is added to 50.0 mL of 1.0M NaOH at 25 °C in a calorimeter, the temperature of the aqueous solution increases to 33.9 °C. Assuming that the specific heat of the solution is 4.18 J/g•°C, that the solution density is 1.00 g/mL, and that the calorimeter itself absorbs a negligible amount of heat, calculate AH (in kJ/mol) for the reaction. H2SO4 (aq) + 2 NaOH (aq) → 2 H2O (I) + Na2SO4 (aq) O -56 kJ/mol -110 kJ/mol O 110 kJ/mol O 56 kJ/mol
