How much potassium chlorate would dissolve in 200g water at 20c

What is the mass defect of a mole of nuclei with 1.8 x 10^15 j/mol binding energy?

Explain in detail of the four major scientific developments that spurred the formulation of the plate tectonics theory

)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.
