A single molecule of water encapsulated in fullerene C60.
A molecule of water consists of two atoms of hydrogen and one of oxygen.
One molecule of water adheres to a tiny ice crystal, and then another.
A single molecule of water has been isolated for the first time by trapping it in a fullerene cage.
When a molecule of water leaves the liquid and becomes airborne -- when it evaporates -- this physical attraction must be broken.
Thus, diphosphoric, or pyrophosphoric, acid (H4P2O7) is formed from two molecules of phosphoric acid, less one molecule of water.
One of these can latch on to a bit of protein, while the other three are free to bind a molecule of water.
A molecule of water is lost in the formation of a peptide from two amino acids or of a disaccharid sugar from two monomers.
Ethanol, the most popular and commercial biofuel, has long been refined out of plant matter, but it requires the costly, energy-intensive step of distilling every molecule of water out of the solution.
Each molecule of water that evaporates into a particular parcel of air as vapor will replace a molecule of either nitrogen or oxygen, which account for roughly 99percentt of the air's gasses.
