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.

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 WebRed and yellow areas indicate the ozone hole. As the images show, the word hole isn’t literal; no place is empty of ozone. Scientists use the word hole as a metaphor for the area in which ozone concentrations drop below the historical threshold of 220 Dobson Units. Using this metaphor, they can describe the hole’s size and depth.
