What are the oxidation states of iron in Fe2O3? What is the oxidation state of CL in HCL? What is the oxidation state of an individual nitrogen atom in NH2OH? What oxidation states can the alkaline earth metals exhibit? How many electrons would 10.0 g \text{Fe}^0 lose when it is ...
This estimate of source Fe2O3 agrees with the estimate for fertile upper mantle lherzolite deduced from measurements of Fe3+/∑Fe and total Fe in the minerals of spinel peridotite xenoliths from the lithosphere.The fO2 of the MORB glasses at 1 bar may be calculated from their measured Fe3...
Magnetic susceptibility and XPS results on xFe2O3 · (100-x) [4Bi2O3 · PbO] where 0<x ≤20 samples are presented in order to point out the oxidation states and the distribution of iron ions in the lead-bismuthate matrix. The valence state of iron ions changes from Fe3+ to Fe2+...

The use of iron oxide as an oxygen carrier has been investigated. Particles composed of 4080 wt % Fe2O3, together with Al2O3, ZrO2, TiO2, or MgAl2O4, have been prepared by freeze granulation. Particles have been sintered at different temperatures in the range of 9501400 °C, and ...
However, in order to obtain metallic iron, the iron oxide has to be reduced from the trivalent (or divalent) state to the metallic one [5]. For this reason, a reducing agent is required which must have a higher affinity to oxygen than the iron itself, under given process conditions [6...

The iron paleochemistry, the phylogeny, the physiology of the iron oxidizers, and the nature of the cofactors of the redox proteins involved in these pathways suggest a possible scenario for the timescale in which each type of Fe(II) oxidation pathways evolved. The nitrate dependent anoxic iron...
