totse.com - All About Ozone - Whenever it occurs, ozone (O ) is a colorless gas, a form of oxygen. However, an ordinary molecule of oxygen contains two atoms while a molecule of ozone contains three atoms ( O + O = O3 ). Because of ozone's composition

Researchers claim they could have flown only if the air had contained more oxygen than today-probably as much as 35 per cent. But oxygen is a toxic gas. Fruit flies raised at twice the normal level of oxygen live half as long as their siblings. If atmospheric oxygen reached 35 per cent...

Neutron scattering by oxygen gas at 100 bar has been measured. The observed differential cross-section at high Q-values is fitted to a form-factor dependent on the molecular geometry. At lower Q-values there are coherent contributions from intermolecular and magnetic correlations. Molecular dynamics...
