Question

when silver tarnishes, it reacts with hydrogen sulfide (h₂s) or oxygen to form silver sulfide (ag₂s) or silver oxide (ag₂o). why is tarnishing considered a chemical property?

Explanation:

Tarnishing involves a chemical reaction. Silver reacts with substances like hydrogen sulfide or oxygen to form new substances (silver sulfide or silver oxide). A chemical property is a characteristic of a substance that is observed during a chemical reaction. Since tarnishing results from a chemical reaction (formation of new substances), it is a chemical property.

Answer:

Tarnishing is a chemical property because it involves a chemical reaction where silver reacts with other substances (like hydrogen sulfide or oxygen) to form new substances (silver sulfide or silver oxide), and chemical properties are observed during chemical reactions.
