1) is the process of separating substances into their individual components a) chramotography  b) adsorption chromatography c) separating pure substance d) partition chromatography 2) stationary phase is thin film of liquid adsorbed on an essentially inert support. Mobile phase may be a liquid or a gas. a) adsorption chromatography b) partition chromatography c) chramotography d) Thin-layer chromatography 3) stationary phase is usually in the form of a packed column (column chromatography) but may take other forms a) thin-layer chromatography b) adsorpition chromatography c) mobile phase d) stationary phase 4) stationary phase is a finely divided solid adsorbent and the mobile phase is usually a liquid a) thin-layer chromatography b) stationary phase c) adsorpition chromatography d) mobile phase 5) any liquid or frozen water that forms in the atmosphere and falls back to the earth. It comes in many forms, like rain, sleet, and snow. a) preciptiition b) mobile phase c) stationary phase d) chromatography 6) examples of precipitition a) sleet b) pure substance c) liquid absorbed unto solid support d) h2o 7) importance of precipitition a) . It supplies water to hydroelectric facilities, which use it to generate energy b) Separation depends upon partition of substance between two phases and the adsorption effects of inert support on compounds undergoing chromatographic separation. c) to separate mixtures of compounds based on differences in polarity. d) non of the following
