The chemical component of water are two molecules of hydrogen and one molecule of oxygen. It's chemical formular is H2O where H = a hydrogen atom, O = an oxygen atom and the 2 is written as a subscript signifying that there are two atoms of hydrogen.
Hope this is useful~

water, as the symbol H2O conveys
is a molecule that consists of two hydrogen atoms and one oxygen atom
so, the chemical component of water could be described as two parts hydrogen, one part oxygen
