)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.

When microscope slides are stained to show blood cells, the small red blood cells that appear on the slides are much numerous than the large white blood cells. this supports the concept that

The half-life of a certain element is 100 days. how many half-lives will it be before only one eighth of this elementremains?
