What is the chemical formula for water?

The chemical formula for water is H2O, which represents two hydrogen atoms bonded to one oxygen atom. Water is a polar molecule, meaning it has a slight electrical charge with the oxygen atom being slightly negative and the hydrogen atoms being slightly positive. This polarity gives water unique properties, such as its ability to dissolve many substances and its high heat capacity. Water is essential for life and is involved in countless biological and chemical processes, making it one of the most important molecules on Earth. It is also a universal solvent, capable of dissolving various substances.
