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.
Tarnish of silver is a chemical change. It occurs when the silver reacts with sulfur compounds in the air to form silver sulfide, creating a darkened appearance on the surface of the silver.
No, tarnishing silver is a physical change. It occurs when silver reacts with sulfur compounds in the air to form silver sulfide on the surface of the silver. This reaction does not change the chemical composition of the silver, only its appearance.
Tarnish on silver is Silver Oxide, which is oxidised silver. This is indeed a chemical reaction.

Tarnish of silver is a chemical change. It occurs when the silver reacts with sulfur compounds in the air to form silver sulfide, creating a darkened appearance on the surface of the silver.
It's a chemical change. A thin layer of silver on the surface reacts with oxygen in the air - to form silver oxide.
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.

Yes, the tendency of silver to tarnish is a chemical change. It occurs when silver reacts with sulfur compounds in the air to form silver sulfide, leading to the discoloration of the metal surface.
