Three liquids of different densities are mixed. Because they are not miscible (do not form a homogeneous solution with one other), they form discrete layers, one on top of the other. Sketch the result of mixing carbon tetrachloride (CCl_4, d = 1.58 g/cm^3, mercury (d = 13.546 g/cm^3), and water (d = 1.00 g/cm^3).
