Mass of Fe=(Mass of Fe2O3)(Mr Fe/ Mr Fe2O3)
fe + O2 = feO
The ferrous oxide is the oxdant.
fe+3=..............* .9 =fe+2
Because Ag2O (as oxidator) is more reactive than FeO, so Fe (as reductor) can abstract the oxide O (O2-) from Ag2O according to electrochemical series (which says: Ag is less reactive to oxygen than Fe, Ag is a more 'noble' metal)Fe + Ag2O --> FeO + 2Ag
+2 for Fe, -2 for O
FeO is 50 mole % Fe and 50 mole % O FeO is 77.73 mass % Fe and 22.27 mass % O mass fraction X = molar mass X / (total molar mass of compound) mass % Fe = [atomic mass Fe] / ([atomic mass Fe] + [atomic mass O])
155.5 grams of Fe are in 200.0 grams of FeO.
feo or fe(a) (feminine)
Mass of Fe=(Mass of Fe2O3)(Mr Fe/ Mr Fe2O3)
Fe
A nail is made of Fe. Rust is FeO. Water is H2O. Fe + H2O ---> FeO + 2 H
The reactions are:4 Fe + 3 O2 + 2 H2O = 4 FeO(OH)2 FeO(OH) -------Fe2O3 + H2O
feo2 feo3 feo4
fe + O2 = feO
Usually metals make ionic bonds with non metals. Fe is a metal compound. So FeO is an ionic compound.
Fe3O4 can be considered to be 1:1 mixture of FeO and Fe2O3. Oxidation number in FeO: +2 for Fe and -2 of O Oxidation number in Fe2O3: +3 for Fe and -2 of O
