Storms in the Bay of Bengal account for seven of the 10 deadliest hurricanes, typhoons and cyclones in recorded history, as documented by Weather Underground. The casualty figures are notoriously difficult to pin down, but here is the list: Bhola cyclone, Bangladesh (East Pakistan), 1970.
Chlorine Basic Facts. Properties: Chlorine has a melting point of -100.98Â°C, boiling point of -34.6Â°C, density of 3.214 g/l, specific gravity of 1.56 (-33.6Â°C), with a valence of 1, 3, 5, or 7. Chlorine is a member of the halogen group of elements and directly combines with almost all of the other elements. Chlorine gas is a greenish yellow. Chlorine figures prominently in many organic chemistry reactions, particularly in substitutions with hydrogen.
Chlorine is produced by the electrolysis of salt water. When electricity is passed through 2NaCl (salt) and 2H20 (water), the atoms dissociate into Cl2 (chlorine) + 2NaOH (sodium Hydroxide) + H2 (Hydrogen). When using a salt chlorine generator on a pool, the pool chlorine is created by the salt cell, a stack of electrically charged plates. When power is applied to these cells, and salty water is pumped through the cell, chlorine is created instantly as the water leaves the salt cell and is pumped into the pool.
