A coffee cup calorimeter having a heat capacity of 451 J/oC was used to measure the heat evolved when 0.0300 mol of NaOH(s) was added to 1000 mL of 0.0300 M HNO3initially at 23.000oC. The temperature of the water rose to 23.639oC. CalculateH (in kJ/mol NaNO3) for this reaction. Assume the specific heat of the final solution is 4.18 J/goC; the density of each solution is 1.00 g/mL; and the addition of solid does not appreciably affect the volume of the solution.
When distilling a pure compound, the boiling temperature remains constant although you are heating the flask. Why?
