Calculate the molar solubility of CaF2 in a solution containing 0.186 M of Ca(NO3)2. The Ksp value for CaF2 is 1.46×10−10.

How many neutrons does a atom of cobalt have?

Temperature is _related to the average kinetic energy of a gas. inversely directly not disproportionally

)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.
