Water = Chemical compound (H2O)
Chlorine Chemical element (Cl)
Iron = Chemical element (Fe)
Calcium = Chemical element (Ca)

So it really sounds like you only consider a single element a chemical and not a compound?

A great site that plays with the semantics of Water being a chemical is http://www.dhmo.org/facts.html.

From the site

Dihydrogen Monoxide (DHMO) is a colorless and odorless chemical compound, also referred to by some as Dihydrogen Oxide, Hydrogen Hydroxide, Hydronium Hydroxide, or simply Hydric acid. Its basis is the highly reactive hydroxyl radical, a species shown to mutate DNA, denature proteins, disrupt cell membranes, and chemically alter critical neurotransmitters. The atomic components of DHMO are found in a number of caustic, explosive and poisonous compounds such as Sulfuric Acid, Nitroglycerine and Ethyl Alcohol.
