what happens to iron when iron oxide becomes elemental iron…

When iron oxide becomes elemental iron, this process is known as reduction. During reduction, the iron oxide loses oxygen, and the iron is reduced from its oxidized form to elemental iron. This is a part of a redox (oxidation-reduction) reaction, where oxidation is the loss of electrons and reduction is the gain of electrons.

What happens to iron when iron oxide becomes elemental iron?

The decomposition of iron oxide to elemental can be represented by the following equation: In iron oxide (Fe2O3), the oxidation state of iron is +3 while that of oxygen is -2. Therefore, the above reaction is a redox (reduction oxidation reaction). Here, iron in iron oxide gains 3 electrons and gets reduced from Fe3+ to Fe(0).
