Answer 1

The correct response is:

They are rearranged.

During a chemical reaction, the atoms of reactants (in this case, Fe and O2) are rearranged to form new products (in this case, Fe2O3), but their individual properties remain the same. The mass of the reactants is conserved in accordance with the law of conservation of mass.
