The Uniform Crime Reports program began in 1930, and since then has become an important source of crime information for law enforcement, policymakers, scholars, and the media.
The molecular formula for water is H2O. One molecule of water consists of one oxygen atom which is covalently bonded to two hydrogen atoms.
The chemical formula is: H2O. One important thing to note is that hydrogen with atomic mass 1 is the most abundant isotope of hydrogen but deuterium (D), a hydrogen isotope with atomic mass 2, is also found in nature so D2O is the chemical formula of heavy water as it is known chemically.
