No, it is a chemical change. The tarnish seen on silver is silver sulfide which formed by the silver reacting from small amounts of hydrogen sulfide in the air. So silver sulfide has been created by a chemical reaction.
No. It is a chemical reaction with hydrogen sulfide in the atmosphere. Silver will not react to just oxygen by itself. See related link.
It is a chemical change because silver react with hydrogen sulfide and black silver sulfide (Ag2S) is formed on the exposed surface.
It is a chemical change.
Silver platter tarnishing is a chemical change: a reaction with hydrogen sulfide.
Chemical Change.--its tarnish!
a physical property
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.

Tarnishing is actually oxidation of the silver, so it would be a chemical change.

Nothing: it is a chemical change and that fact cannot be altered.
It's a chemical change. The silver reacts with sulfur compounds from the air.
