salt plus water. two compounds mixed together to form a solution. The water is the solvent; the salt is the solution. students have been tasked with separating the two compound from solution.

What are the similarities of physical and chemical change ?

)benzene and toluene form nearly ideal solutions. consider an equimolar solution of benzene and toluene. at 20 °c the vapour pressures of pure benzene and toluene are 9.9 kpa and 2.9 kpa, respectively. the solution is boiled by reducing the external pressure below the vapour pressure. calculate (i) the pressure when boiling begins, (ii) the composition of each component in the vapour, and (iii) the vapour pressure when only a few drops of liquid remain. assume that the rate of vaporization is low enough for the temperature to remain constant at 20 °c.

Is the flow of energy during vaporizing more like the flow during melting or during freezing
