As expected, the Fe 2 O 3 –NG/GCE shows extraordinary electroalytic oxidation capacities toward DA and UA over two wide dynamical response concentration ranges of –10 μM and 10–100 μM, with low detection limits (LOD) of and μM for DA and UA, respectively. Moreover, the Fe 2 O 3 –NG/GCE shows high antiinterference ability against several potential interferences and ...
· The oxidation number of iron depends on the oxide. +2 for Fe in FeO. +3 for Fe in Fe2O3. +2 and +3 for Fe in Fe3O4. (Note: Fe3O4 can be considered as a mixture of FeO and Fe2O3.

· The Fe2O3/FeO ratio is a challenging variable of chemical analysis where all Fe is measured as Fe2O3. Depending on the initial nature of your rocks of interest it will vary.
· The Al K alpha, eV, based xray photoelectron spectroscopy (XPS) of Fe 2p and Fe 3p for Fe(III) in Fe 2 O 3 and Fe(II) in FeO is compared with theoretical predictions based on ab initio wavefunctions that accurately treat the final, corehole, multiplets. The principal objectives of this comparison are to understand the multiplet structure and to evaluate the use of both the 2p and 3p ...
Answer: Fe = 72%; O = 28% in 1 g mixture we have g Fe and g O Fe in the mixture= 2Fe + Fe = g Fe = in Fe2O3 there are : x2 = g Fe and O = 3O + O = g O = g In Fe2O3 there are 3O = g the mass of Fe2O3 in the mixture is + = g verifi...
