Question

How can we get $F{{e}_{2}}{{O}_{3}}$ and $FeO$ from $Fe$ ?

Answer 1

Hint : We know that iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually wealthy in iron oxides. Also, it varies in colour from bright yellow, dark grey, or deep purple to rusty red.

Complete Step By Step Answer:
Iron $\left( III \right)$ oxide or ferric oxide is the inorganic compound with the formula $F{{e}_{2}}{{O}_{3}}$ . It is one of the three main oxides of iron, the other two being iron $\left( II \right)$ oxide, which is rare; and iron $\left( II,\text{ }III \right)$ oxide, which also occurs naturally as the mineral magnetite.
$FeO$ : Iron $\left( II \right)$ oxide or ferrous oxide is the inorganic compound with the formula $FeO$ . Its mineral form is known as wurtzite. One of several iron oxides, it is a black-colored powder that is sometimes confused with rust, the latter of which consists of hydrated iron $\left( III \right)$ oxide. The chemical reaction is given by;
$2F{{e}_{(s)}}+{{O}_{2(g)}}\to 2Fe{{O}_{(s)}}$
$F{{e}_{2}}O$ : The oxidation is the process involved in the ferrous oxide. The iron ion $F{{e}^{+3}}$ oxidation number is (three). And for the oxide ion the ${{O}^{2-}}$ oxidation number is three. The oxidative summation of the iron ion and the oxygen ion equals to zero. The chemical reaction is given by;
$3F{{e}_{(s)}}+2{{O}_{2(g)}}\to F{{e}_{3}}{{O}_{4(s)}}$

Note :
Note that as the mineral known as hematite, $F{{e}_{2}}{{O}_{3}}$ is the main source of iron for the steel industry. $F{{e}_{2}}{{O}_{3}}$ is readily attacked by acids. Iron $\left( III \right)$ oxide is often called rust, and to some extent this label is useful, because rust shares several properties and has a similar composition; however, in chemistry, rust is considered an ill-defined material, described as hydrated ferric oxide.
