Shares & Saves. Save. Xenon and halogen lights use a gas to help increase bulb effectiveness, but there are several key differences between them. Halogen lights are an older type of bulb that uses halogen gas primarily as a buffer and backup system, while xenon lights depend wholly on xenon gas to produce light.
Magnesium chloride is the name for the chemical compounds with the formulas MgCl 2 and its various hydrates MgCl 2 (H 2 O) x. These salts are typical ionic halides, being highly soluble in water. The hydrated magnesium chloride can be extracted from brine or sea water.
These metals â like beryllium, magnesium, calcium and strontium â will react with hydrochloric acid to form a chloride and free hydrogen. Metallic magnesium when combined with hydrochloric acid, will naturally result in magnesium chloride -- used as a dietary supplement -- with the hydrogen being released as a gas.ydrochloric acid, however, will also react with these metals â for instance, two molecules of hydrochloric acid and two atoms of metallic sodium will react to produce two molecules of sodium chloride (table salt) and one molecule of hydrogen gas.
