At room temperature, bromine trifluoride (BrF 3) is a straw-coloured liquid. It may be formed by directly fluorinating bromine at room temperature and is purified through distillation. It reacts violently with water and explodes on contact with flammable materials, but is a less powerful fluorinating reagent than chlorine trifluoride.
Inorganic bromine is found in the atmosphere and is quickly cycled between its gas and its particulate phase. Bromine gas (Br 2 ) undergoes an autocatalytic cycle known as the ' bromine explosion ', which occurs in the ocean and salt lakes such as the Dead Sea , where a high quantity of salts are exposed to the atmosphere.
Antoine Jérôme Balard met John Stuart Mill while Mill was studying at the Montpellier Faculty of Sciences in the Winter of 1820. In Mill's journal of the period [9] he writes of visiting Balard at his home, being shown his herbarium and receiving from him a selection of his plants from the Montpellier area, in addition to other accounts of the two embarking on daytrips around the city of ...

However, ocean currents also flow thousands of meters below the surface. These deep-ocean currents are driven by differences in the water's density, which is controlled by temperature (thermo) and salinity (haline). This process is known as thermohaline circulation. In the Earth's polar regions ocean water gets very cold, forming sea ice.
