Why do we name compounds?

The primary function of chemical nomenclature is to ensure that a spoken or written chemical name leaves no ambiguity concerning which chemical compound the name refers to: each chemical name should refer to a single substance.

What are chemical formulae?

These are called chemical formulae. In the first three examples, the ratio of the elements in each compound is 1:1. So, for FeS, there is one atom of iron for every atom of sulfur in the compound. In the last example ( H 2 O) there are two atoms of hydrogen for every atom of oxygen in the compound.
