Calculate the heat of sublimation of solid carbon dioxide (dry ice) given that the enthalpy of fusion of solid carbon dioxide is 8.6 kJ/mol and the enthalpy of vaporization of carbon dioxide gas is 22.8 kJ/mol. (Hint: The heat of sublimation of a substance is equal to the sum of its enthalpy of fusion and enthalpy of vaporization.)

A chemistry student needs to determine the composition of a sample that contains an unknown mixture of sodium chloride (NaCl) and potassium chloride (KCl). The student weighs 2.00 g of the mixture and dissolves it in water to obtain a solution. The student then precipitates the chloride ions from the solution with excess silver nitrate (AgNO3) to obtain 6.50 g of silver chloride (AgCl). Using mass balance calculations, determine the mass and percentage composition of the sodium chloride and potassium chloride in the mixture.
