When 109.0 g of glycine C2H5NO2 are dissolved in 1050.0 g of a certain mystery liquid X, the freezing point of the solution is 6.1 °C lower than the freezing point of pure X. On the other hand, when 109.0 g of sodium chloride are dissolved in the same mass of X, the freezing point of the solution is 11.9 °C lower than the freezing point of pure X.
Calculate the van't Hoff factor for sodium chloride in X.

Cryolite, na3alf6(s), an ore used in the production of aluminum, can be synthesized using aluminum oxide. start this question by first balance the chemical equation.1.) balance the equation: - alo3(s)+naoh(l)+hf(> na3alf6+h2o(g). 2.) if 17.5 kilograms of al2o3(s), 51.4 kilograms of naoh(l), and 51.4 kilograms of hf(g) react completely, how many kilograms of cryolite will be produced? 3.)which reactants will be in excess, (al2o3, naoh, or hf) 4.)what is the total mass of the excess reactants left over after the reaction is complete in kg?
