Most cars use water to cool their engines. Ethylene glycol, propylene glycol, or methanol may be added to the water, especially in harsh climates. Why are these added to the water? A) They lower the specific heat of water, allowing it to absorb more energy. B) They lower the freezing point of the water, preventing cracking due to the formation of ice. C) They render the water poisonous to keep animals from gnawing through pipes to reach the water. D) They raise the freezing point of the water, allowing it to more easily turn to ice and cool the engine.

)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.
