Elemental chlorine has since served a continuous function in topical antisepsis (wound irrigation solutions and the like) and public sanitation, particularly in swimming and drinking water. [18] Chlorine gas was first used as a weapon on April 22, 1915, at the Second Battle of Ypres by the German Army.
Chlorine, along with phosphorus, is the sixth most common element in organic matter. [1] Cells utilize chloride to balance pH and maintain turgor pressure at equilibrium. The high electrical conductivity of Cl − ions are essential for neuron signalling in the brain and regulate many other essential functions in biology [ 9 ]
This list is sorted by boiling point of gases in ascending order, but can be sorted on different values. "sub" and "triple" refer to the sublimation point and the triple point, which are given in the case of a substance that sublimes at 1 atm; "dec" refers to decomposition. "~" means approximately. Blue type items have an article available by ...
A biogeochemical cycle, or more generally a cycle of matter, [1] is the movement and transformation of chemical elements and compounds between living organisms, the atmosphere, and the Earth's crust. Major biogeochemical cycles include the carbon cycle , the nitrogen cycle and the water cycle .
Geochemistry is the science that uses the tools and principles of chemistry to explain the mechanisms behind major geological systems such as the Earth's crust and its oceans.
Non condensible gases and remaining chlorine gas are vented off as part of the pressure control of the liquefaction systems. These gases are routed to a gas scrubber, producing sodium hypochlorite, or used in the production of hydrochloric acid (by combustion with hydrogen) or ethylene dichloride (by reaction with ethylene).
Earlier this week, the chlorine smoke closed schools and led to a shelter-in-place order for more than 90,000 residents east of Atlanta while some were told to evacuate after emergency officials ...
Often encountered are atomic oxygen (O nasc), nascent hydrogen (H nasc), and similar forms of chlorine (Cl nasc) or bromine (Br nasc). The concept of a "nascent state" was developed to explain the observation that gases generated in situ are frequently more reactive than identical chemicals that have been stored for an extended period of time.
