Answer:
true
Explanation:
A chemical reaction with the silver of flatware, jewelry, or other silver objects can change their beautiful lustrous sheen to a dull, blackened surface. This dark coating is called tarnish. Compounds in the air and in foods can contact silver metal and react to form tarnish.

Answer:
TRUE
Silver tarnishing is a chemical change since the silver is chemically turning into silver sulfide. Chemical changes must involve a reaction. A hint that this is a chemical reaction is that there is a color change involved (from silver to black), and the tarnish can be removed without removing the unreacted silver.
