Calcium cyanide | Ca(CN)2 - PubChem
The alkaline earth metal cyanides can be obtained by reaction of the corresponding metal hydroxides with hydrogen cyanide. However, only liquid calcium cyanide is produced by this method. The resulting product has a brownish color due to polymerization of HCN, liberated by hydrolysis.

Oxygen - Element information, properties and uses | …
Oxygen accounts for about 23% of the atmosphere''s mass with pairs of oxygen atoms stuck together to make dioxygen molecules, but it''s not just in the air, we breathe. Overall, it''s the most abundant element on the earth''s surface and the third most abundant in the universe after hydrogen and helium.
OXYGEN EVOLUTION - Photobiology
Calcium and Cl-are both required for oxidation of the Mn atoms by chlorophyll photochemistry. Omission of Cl - blocks the S 2 --> S 3 transition (Wincencjusz et al., 1997), and Ca 2+ is required for all of the transitions except perhaps S 0 --> S 1 (Miqyass et al., 2008).

The Effects of Oxidation on Copper | Sciencing
This layer of oxidation doesn''t securely stick to the surface of the iron. It flakes off, weakening the metal and leaving it vulnerable to further rusting and structural decay. Copper oxidation, on the other hand, prevents further oxygen exposure and corrosion by solidly adhering to the metal''s surface.
