WebApr 24, 2001 · Use it a few times and you begin to think you know what it means. If there is more oxygen than present with iron and FeO, there will be no metallic iron present. You would get the quartz-fayalite-magnetite combination at an oxygen pressure over a thousand times higher (three log units) than when only iron metal and FeO are present. WebExample #1: FeO. Step #1 - the first part of the name is the root of the first element in the formula plus a suffix. For iron the root to use is "ferr-". The suffix will be either "-ous" or "-ic." Here is how to determine the suffix. multiply the charge of the anion (the O) by its subscript. Ignore the fact that it is negative. WebUseful for determining theoretical iron speciation when total is given as FeOtotal or Fe2O3total and fO2 is known.
