The balanced equation is:


2Fe_2O_3\text{ }+3C\rightarrow3CO_2+4Fe

This is a single replacement reaction (S.R.) because one element (in this case iron) is substituted for another element (in this case carbon) in the compound.

The starting materials are 1 pure element (C) and a compound (Fe2O3), and after the reaction the pure element changes (Fe) and also the compound (CO2).
