Question

23 is the ability to rust a physical or chemical property?

Explanation:

To determine if the ability to rust is a physical or chemical property, we recall the definitions: Physical properties can be observed without changing the substance's chemical identity, while chemical properties relate to a substance's ability to undergo chemical reactions (forming new substances). Rusting involves iron reacting with oxygen and water to form iron oxide (a new substance), so it's a chemical property.

Answer:

The ability to rust is a chemical property.
