How do polar molecules respond when they are placed between two metal plates, one positively
harged and one negatively charged?
The molecules break apart as atoms migrate to the two plates,
The molecules join together, forming one large molecule.
The molecules align to the electric field.
The molecules spin in circles.

)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.
