Talk:Flameless ration heater
From Wikipedia, the free encyclopedia
Took the liberty of moving this back to FRH. I'd go with "flameless ration heater" if FRH were a disambig page, but for now I think it's best to go with "most common name in English." - Hephaestos|ยง 15:49, 6 Mar 2004 (UTC)
[edit] Valence electrons
The role of iron in the heater is most likely as a catalyst, since it is used in a small amount. In this case, the iron is initially oxidized, and then reduced back to its elemental form as the magnesium is oxidized and sends its two valance electrons to iron
Wouldn't the two valence electrons from the magnesium atom go to the oxygen atom? - KingRaptor 06:34, 8 August 2006 (UTC)
How long has the FRH been around? I don't remember it from MREs in the early 90's, but I only had them a few times and may have just not used it.
