Tarnishing of silver is the same process as rusting of steel . . . they are both chemical processes involving the formation of compounds with oxygen.
Removing tarnish from a penny with salt and vinegar is a chemical change. The reaction between the salt, vinegar, and tarnish on the penny results in the formation of new substances that remove the tarnish.
The ability to tarnish is a chemical property. Tarnishing occurs when a substance undergoes a chemical reaction with other compounds in its environment, leading to the formation of a different substance on its surface.
Chemical.
Silver reacts with sulfur compounds in the air to form a black tarnish layer called silver sulfide. This tarnish layer can be easily wiped off with a polishing cloth or a chemical cleaner to restore the silver's shine.
Tarnishing is a chemical change as it involves a reaction between the metal and substances in the environment, leading to the formation of a new compound on the metal surface. This new compound is often a metal oxide or sulfide, which gives the tarnished appearance.

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.
No, it's a chemical property.
Removing tarnish from a penny with salt and vinegar is a chemical change. The reaction between the salt, vinegar, and tarnish on the penny results in the formation of new substances that remove the tarnish.
Physical change
The ability to tarnish is a chemical property. Tarnishing occurs when a substance undergoes a chemical reaction with other compounds in its environment, leading to the formation of a different substance on its surface.
1. Mechanically removing: physical process 2. Chemically removing: chemical process
It's a chemical change because a new substance comes out of tarnishing.
