Chemical compound with raw molecular formula H₂O; main constituent of the fluids of most living organisms
Water (chemical formula H 2 O) is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent). It is vital for all known forms of life, even though it provides neither food energy nor organic micronutrients. Wikipedia
