A particulate drawing of a single Cu^2+ ion is shown in the following box. Draw two H2O molecules in the box to show the most likely orientation of H2O(l) molecules around Cu^2+ ion.

Substance a is a nonpolar liquid and has only dispersion forces among its constituent particles. substance b is also a nonpolar liquid and has about the same magnitude of dispersion forces among its constituent particles. when substance a and b are combined, they spontaneously mix.
