2018-3-5 · There are two components: the reduced element and the reducing agent. When the above compound, tin, accepts carbon electrons in the reaction tin dissociates with oxygen forming carbon monoxide. Tin is reduced ; Oxidation occurs when an element gains electrons in which the extra electrons, coming from the oxygen are given to the magnesium
The two most common reducing gas constituents in a protective atmosphere are hydrogen and carbon monoxide. Carbon monoxide is a constituent of generated endo and exo atmospheres, typically used when metals are being treated (carburized) to increase their carbon level to harden them – examples might include saw blades or gears.

Mg = reducing agent, donates electrons, reduces 2H⁺ to H₂, Mg is oxidised itself Ba(OH)₂ is the most soluble Group 2 hydroxide. Be(OH)₂ is completely insoluble, but after that, as you go down group 2 the solubility of the M(OH)₂ increases
For example, carbon monoxide (CO) specifically inhibits a nuer of oxidizing enzymes that contain iron or copper in their active centers. Carbon monoxide forms a chemical compound with these metals, blocks the enzyme’s active center, and consequently halts the enzyme’s activity. The inhibition of enzymes can be reversible or irreversible.
