Question 4

50.0 mL of 2.00 mol/L HNO3 solution and 50.0 mL of 1.00mol/L NaOH solution, both at 20.0 degree Celsius, were mixed in acalorimeter. Calculate the molar heat of neutralization ofHNO3 in kJ/mol if:

(1) final temperature was 27.1 degree Celsius;

(2) the mass of the overall solution was 102.0 g;

(3) the heat capacity of the calorimeter was 25.0 J/C;

(4) and assume that the specific heat of solution is the same aswater, 4.184 J/(g C);

Question 5

In part IIA, a student unknowingly spilled a few drops of NaOHsolution. How will the spill affect the molar heat ofneutralization?

The molar heat of neutralization will be higher than what itshould be.

The molar heat of neutralization will be lower than what itshould be.

A very small amount of spill of NaOH should not have any impacton the molar heat of neutralization
