We use numerous chemical compounds in
our daily. It may be a salt in your food or sugar in your tea. These common chemical compounds play
a helpful role in our life.
As each and every thing in this
universe has a distinct identity, so are the chemical compounds.
Every chemical compound has a
distinct chemical name (common name also) and a chemical formula associated with
it.
The chemical formula of common
chemical compounds is discussed here.
Definitions :
Chemical Compound
A chemical compound
is composed of two or more constituent atoms / ions bonded together chemically
in a fixed ratio.
