Choose the option below that is characteristic of a solution. Select the correct answer below: The solute can be present in any concentration in a solid-liquid solution. It is sometimes heterogeneous. Its composition and the concentrations of its components fluctuate. Its physical state is generally the same as that of the solvent.

Why do sodium and neon have vastly different chemical and physical properties despite having similar atomic masses?

1. suppose a reaction mixture, when diluted with water, afforded 300 ml of an aqueous solution of 30 g of the reaction product malononitrile [ch2(cn)2], which is to be isolated by extraction with ether. the solubility of malononitrile in ether at room temperature is 20.0 g/100 ml, and in water is 13.3 g/100 ml. what weight of malononitrile would be recovered by extraction with (a) three 100-ml portions of ether and (b) one 300-ml portion of ether? suggestion: for each extraction, let x equal the weight extracted into the ether layer. in part (a), the concentration in the ether layer is x/100 and in the water layer is (30 x)/300; the ratio of these quantities is equal to k 20/13.3.
