Answer

Brief Explanations:

In a chemical reaction, new substances with different properties are formed. Iron(III) oxide has different melting points, densities, and appearances compared to iron and oxygen. This indicates a chemical reaction occurred.

Answer:

C. A chemical reaction occurred because iron(III) oxide has different properties than iron and diatomic oxygen.
