solubility of gas solutes in water as temperature increases such as CO2 or O2 gas and explain why using the collision theory.

Explain what happens at the saturation point when adding salt to water at room temperature.

)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.

Heat is the total potential energy of a substance that can be transferred. true false
