Question

Does the reaction for Fe₂⁺O₃ represent a physical change?
1) True
2) False

Answer 1

The reaction for Fe2+O3 represents a chemical change. Iron reacts with oxygen to form iron(III) oxide, resulting in a change in color and the formation of a new compound.

Step-by-step explanation:

The reaction for Fe2+O3 represents a chemical change. When iron (Fe) reacts with oxygen (O2) to form iron(III) oxide (Fe2O3), new substances are formed with different properties from the reactants. The change in color from dark grey to orange flaky substance and the formation of a new compound indicate a chemical change.
