How did ozone form
WebBefore photosynthesis evolved, Earth's atmosphere had no free oxygen (O 2). Small quantities of oxygen were released by geological and biological processes, but did not build up in the atmosphere due to reactions with reducing minerals..

It is a pale blue gas with a distinctively pungent smell. It is an allotrope of oxygen that is much less stable than the diatomic allotrope O 2, breaking down … Ver mais In 1785, Dutch chemist Martinus van Marum was conducting experiments involving electrical sparking above water when he noticed an unusual smell, which he attributed to the electrical reactions, failing to realize that he had in fact created ozone. Ver mais According to experimental evidence from microwave spectroscopy, ozone is a bent molecule, with C2v symmetry (similar to the water molecule). … Ver mais Ozone is a bent triatomic molecule with three vibrational modes: the symmetric stretch (1103.157 cm ), bend (701.42 cm ) and antisymmetric … Ver mais The trivial name ozone is the most commonly used and preferred IUPAC name. The systematic names 2λ -trioxidiene and catena-trioxygen, valid IUPAC names, … Ver mais Ozone is a colourless or pale blue gas, slightly soluble in water and much more soluble in inert non-polar solvents such as carbon tetrachloride or fluorocarbons, in which it forms a blue solution. At 161 K (−112 °C; −170 °F), it condenses to form a dark blue Ver mais Ozone is among the most powerful oxidizing agents known, far stronger than O2. It is also unstable at high concentrations, decaying into ordinary diatomic oxygen. Its half-life varies with atmospheric conditions such as temperature, … Ver mais
