Water is made up of hydrogen and oxygen, as the others have said.  However, although water is technically a chemical we do not think of it as one.  After all, it is not man-made.  It exists in nature.  So by the scientific definition it may be a chemical, but not by the layman's definition.

Water is most certainly a chemical compound consisting of two atoms of hydrogen bonded to one oxygen atom. It is an important chemical compound that life depends on. It is the universal solvent and living cells consist mainly of water, with other substances dissolved in the cytoplasm. Water is necessary for photosynthesis and the process of hydrolysis depends on water.

Technically, water is a chemical substance.  It has a specific make up of two hydrogen atoms and one oxygen atom.  It is used in specific chemical processes and formulas.  We can recognize it's chemical formula and make-up.  By strict scientific definition, water is a chemical.  However, most people do not think of water as a chemical.  I would argue that most people think of water as an element. 

Air, on the other hand, is not a chemical.  It is made up of many different chemicals.  This is easy to see when we realize that air can have many different compositions.  Air in one area might not be the same as air in another.  Air is a term that we apply loosely to many different combinations of chemicals.
