If 4 moles of gas are added to a rigid container that already holds 1 mole of gas, how will the pressure change inside the container

In apex! a liquid heated beyond a certain temperature becomes

Under normal conditions, describe how increasing the temperatures effects the solubility of a typical salt

)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.
