In the given chemical reaction: 4Fe + 3O2 → 2Fe2O3, the atoms of iron (Fe) and oxygen (O2) undergo changes.
- Fe: Initially, there are 4 atoms of iron (Fe) on the left-hand side (reactant side) of the equation. After the reaction, there are still 4 Fe atoms but they have rearranged to form 2 molecules of Fe2O3. So, the Fe atoms remain the same in terms of quantity but have combined to form a different compound, iron(III) oxide (Fe2O3).
- O2: Initially, there are 3 molecules of oxygen (O2) on the left-hand side of the equation. After the reaction, the 3 molecules of O2 have been consumed and have transformed into 2 molecules of Fe2O3. So, all the oxygen atoms from the O2 molecules have combined with the iron atoms to form iron(III) oxide, Fe2O3.
Therefore, in this reaction, the atoms of iron (Fe) have remained the same in quantity but have rearranged to form a different compound, while the oxygen (O2) atoms have combined with the iron atoms to form the iron(III) oxide compound.
