Iron powder and sulfur powder combined physically; therefore, they retained their individual properties.

Pippy · Answer 2

Iron powder and sulfur powder combined physically; therefore, they retained their individual properties.

Explanation:

Iron combines with sulfur physically as such there is no change in the individual chemical property of iron and sulfur. Iron has magnetic property and sulfur does not. So iron. gets attracted by the magnet and can be separated from sand. In a chemical process the reactants combine chemically to form a new product that has chemical properties distinct from the parent compounds. In a physical combination process no new chemical product is formed with distinct properties from the parent compound.
