Question 4 (1 point) A 1.5 grams sample of rice is placed in a calorimeter. When the sample is burned, the
rice's energy value is 2.81 kcal/g. How many kilojoules of heat is given off by the
rice?

The freezing point depression can be calculated using the pure solvent freezing point and the molality of the solution.

At the freezing point, the vapor pressure of both the solid and liquid form of a compound must be equal.

The freezing point of a substance is the temperature at which the solid and liquid forms are in equilibrium.

To reattain equilibrium, the freezing point of the solute and solvent mixture is lowered relative to the original pure solvent.
