Use the chemical reaction to answer the question. 4Fe + 3O2 - 2 Fe2O3

Question

What happens to atoms of Fe and O2 during the reaction? A. they are lost. B. they maintain their properties. C they are rearranged. D. they gain mass.

Answer 1

The correct answer is C. they are rearranged.

During the chemical reaction, atoms of iron (Fe) and oxygen (O2) rearrange to form iron(III) oxide (Fe2O3). The atoms themselves do not disappear or gain mass; rather, they change their arrangement to form new products.
