What is the cemical equation for water?

The chemical equation for water is H2O, which represents one molecule of water. This equation shows that water is composed of two hydrogen atoms bonded to one oxygen atom. The chemical formula H2O indicates that there are two hydrogen atoms (H) and one oxygen atom (O) in each molecule of water. Water is a polar molecule, meaning that the oxygen atom has a slight negative charge while the hydrogen atoms have a slight positive charge. This polarity gives water unique properties such as its ability to dissolve many substances and its high surface tension.
