In the given chemical reaction:
\[ 4 \text{Fe} + 3 \text{O}_2 \rightarrow 2 \text{Fe}_2\text{O}_3 \]
the correct response is:
**They are rearranged.**
During the reaction, the atoms of iron (Fe) and oxygen (O2) are rearranged to form a new compound, iron(III) oxide (Fe2O3), but the total number of atoms is conserved.
