Chemical formula for water H2O. It is two molecule of hydrogen and one molecule of oxygen.

H2O is the chemical formula for water.

Because water is a combination of two molecules of hydrogen and one molecule of oxygen.

As the valency of H is 1 and that of O is 2 by cross method we get H2O.

2(-1)+2 =0. The molecule of water arise by two atoms of hydrogen and one atom of oxygen. While relatively small quantities of water appear to be colorless, water's tint becomes a deeper blue as the thickness of the observed sample increases. The blue hue of water is an intrinsic property and is caused by selective absorption and scattering of white light. Impurities dissolved or suspended in water may give water different colored appearances.

Cause it contains two hydrogens and one oxygen atom in it.

Water contains two hydrogen atom and one oxygen atom.

2 Atom of Hydrogen & 1 Atom of Oxygen combines to form Water.

When two molecules of hydrogen combine with one molecule of oxygen, the compound formed is water which chemical symbol is H2O.

The two molecules of hydrogen and one oxygen molecule compounds water.
