Unlike most chemical changes, most physical changes are easily reversed. When Adrian's teacher dissolves some sugar in a beaker

of water, the process involves a physical change. Adrian is asked to recover just the sugar in the solution. How can Adrian do this?

Answer:

By heating the solution

Explanation:

Physical changes and chemical changes are the two types of changes that a substance undergoes. Physical change does not alter the substance's chemical composition, hence, can be easily reversed. There is also no new product formed. This is contrary to the occurrences of a chemical change, which cannot be reversed after a new product has been formed.

A physical change is what occurs when Adrian's teacher dissolves some sugar in a beaker of water to form a sugar solution. This change does not involve any new product formation, hence, can be reversed. The sugar can be derived back from the solution by HEATING THE SOLUTION. The water (solvent) will evaporate and the sugar (solute) will precipitate.

Aside from silica gel and alumina what other stationary phase can you use in chromatography​
Svetlanka [38]

Answer:

Paper

Explanation:

In chromatographic separation, two different phases are important; a stationary phase and a mobile phase.

The stationary phase is the phase that does not move. Substances are separated based on how fast or slowly they move in the stationary phase.

The mobile phase is usually the solvent(or mixture of solvents) that carries the solutes through the stationary phase.

The stationary phase is usually composed of a porous material. Paper is a porous material. The mobile phase is trapped between the cellulose fibers of the paper and separation is achieved.
