### reduction half reactions? Yahoo Answers

Sep 09, 2013 · First of all find out the reduction half reactions of each reaction: A) On left side, Cu has +2 ON(oxidation number), it gains 2 electrons from Fe and converts to Cu with zero ON. It is reduced in other words. Thus the reduction half reaction is:(Cu^2+) + (2e) > Cu. Now check out its reduction potential value in the list you have been given.

Subjects'' serum metal values were normally distributed. We found significant correlations between high Cu/Zn ratios and deficits in femoral bone mineral density, measures of speed and strength, muscle mass and hematocrit. High Cu/Zn ratios were also correlated with decreased triglycerides and increased reliance on ADL assistance.

### Oxidizing and Reducing Agents Purdue University

The permanganate ion removes electrons from oxalic acid molecules and thereby oxidizes the oxalic acid. Thus, the MnO 4ion acts as an oxidizing agent in this reaction. Oxalic acid, on the other hand, is a reducing agent in this reaction. By giving up electrons, it reduces the MnO 4ion to Mn 2+.. Atoms, ions, and molecules that have an unusually large affinity for electrons tend to be good
