Ability to rust is a chemical change as it forms a new substance- hydrate ferric oxide. It is also irreversibe.
Tarnishing is considered a chemical change. :)

Neither. Tarnishing is a chemical change. The ability to tarnish is a chemical property.
The actual tarnishing action is a chemical change, as a new compound (silver oxide) is formed.
Chemical Change duuh. Go to science class dumby.
Yes. Silver tarnishing is a chemical change.

No, it's a chemical property.

It's a chemical change because a new substance comes out of tarnishing.
chemical, because when a penny is tarnished its a chemical change because, its weathered down its destroyed. The tarnish itself is usually either the oxide and/or sulfide of the underlying metal.
Solubility is the physical property.
Chemical Change.--its tarnish!

It is a chemical change. Oxygen from the air combined chemically with the silver to form silver oxide- that is the tarnish.
The tarnishing of silver is due to a reaction with hydrogen sulfide. Because the end result of the tarnish is silver sulfide, it is a chemical change.
