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.
What is the ratio of hydrogen atoms to oxygen atoms in a water molecule? There are 3 total atoms in water, which is H2O. There are 2 hydrogen atoms (H), and 1 oxygen atom, so the ratio of hydrogen to oxygen is 2H:1O. Making the world better, one answer at a time.
