ABSTRACT
All of matter and all of life are all about the vast variety of molecules composing matter and living organisms. We are rightfully highly impressed by the remarkably complex molecules of DNA composed of billions of atoms that make up the genetic code of organisms. Chemists are constantly trying to synthesize new molecules, such as those in pharmaceuticals that may be extremely complex and šendishly difšcult to make. But among all molecules, one stands out for its diversity, its occurrence throughout the environment, its vast variety of uses, and its role as a medium for life. This is the molecule of water, which has the very simple formula of H2O. Essential for life, useful for a vast variety of applications, and totally recyclable, water is the ultimate green chemical compound.
