WebUsually, Fe in oxides will be in either +2 oxidation state or in +3 oxidation state. Fe0.94O is a non-stoichiometric compound. A non-stoichiometric compound is that in which the … WebThe low chromium-to-iron ratio of chromite ores is an important issue in some chromite deposits. The value of the chromite ore is indeed dictated in the market by its iron, as well as its chromium content. In the present study, a chromite concentrate was reprocessed by gravity (spiral concentrator) and magnetic separation to enhance the chromium-to-iron …

WebSamples of the iron oxides Fe0.94O, Fe3O4, Fe2O3, and Fe2SiO4 were prepared by high temperature equilibration in controlled gas atmospheres. The samples were fractured in vacuum and high resolution XPS spectra of the fractured surfaces were measured. The peak positions and peak shape parameters of Fe 3p for Fe2+ and Fe3+ were derived … Web8 apr. 2024 · We know that oxidation no. of nitrogen = − 3 and that of Hydrogen = + 1. We know that as a whole compound is neutral, i.e. total charge on compound is zero. So on equating we will get x + 1 − 3 = 0. x = + 2. Therefore the oxidation number of C in H C N is 2 . So, the answer to this question is option A i.e. + 2 .
