. It is chemically resistant to most strong acids, mild alkalies, organic solvents, wet or dry chlorines, bromine and other halogens and is also used extensively in the conveyance of high purity deionized water due to its absence of colorants or additives. Because of its outstanding mechanical...
Ozone depletion is caused by chemicals containing the elements chlorine and bromine, which are halogens. They are important components of a class of refrigerants called chlorofluorocarbons (CFCs) that were in heavy use in the mid 20th century. CFCs are inert and able to migrate to the upper atm...
depths between 130 and 330 feet (40 and 100 metres), the water had a uniform temperature of about 72 °F (22 °C) and a higher degree of salinity (approximately 332 parts per thousand); it contained hydrogen sulfide and strong concentrations of magnesium, potassium, chlorine, and bromine....
In the presence of oxidants (NaNO3, NaNO2, KClO3, PbO2), the reaction to form tungstate is more violent. It can combine with oxygen, fluorine, chlorine, bromine, iodine, carbon, nitrogen, sulfur, etc. at high temperature, but not with hydrogen.The following is the reaction equation of tun...
The non-reactive coolant has little or no hydrogen. To liquefy a reactive gas e.g. chlorine, in a heat transfer unit (4), the heat transfer unit is cooled by a non-reactive coolant which is free of chlorine or bromine. The non-reactive coolant has little or no hydrogen. The coolant ...
