Question #a5e9d + Example - Socratic

02.07.2016· Ca(s) +Br2(l) → CaBr2(s) This is a redox reaction in which calcium is being oxidized, its oxidation state going from 0 to +2, and bromine is being reduced, its oxidation state going from 0 to −1. 0 Ca(s) + 0 Br2(l) → +2 Ca−1 Br2(s) Now, I think that this reaction actually involves gaseous bromine.

The Nutritional Relationships of Copper - Trace Elements

copper deficiency include a loss of trabecular formation with thinning of the cortex. It is common to find low tissue levels of calcium in conjunction with low tissue levels of copper on TMA studies. Through TMA studies, osteoporosis has been linked with both copper deficiency and copper

Heavy Metals: Oxidation and Metal Staining

Water is the universal solvent, and can eventually dissolve just about anything. Yes, this includes metal minerals like calcium and magnesium, and it also includes heavy metals like copper, iron, manganese and silver. Unlike minerals (calcium and magnesium), heavy metals are oxidants, which means they get oxidized in the presence of chlorine.
