Is tarnish of silver a physical or chemical change?
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.
Is the tendency of silver to tarnish a chemical change?
Yes. Silver tarnishing is a chemical change.
What about tarnishing of silver is chemical or physical change?
It's a chemical change. A thin layer of silver on the surface reacts with oxygen in the air - to form silver oxide.
Is tarnish of silver physical or chemical change?
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.
What happens when silver is exposed to air?
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.
What is the chemical equation of the tarnish of silver?
The tarnish of silver is mainly caused by the formation of silver sulfide (Ag2S) when silver reacts with sulfur compounds in the air. The chemical equation for this reaction is: 2Ag + H2S + O2 → Ag2S + H2O
Is silver tarnishing chemical change or chemical property?
Tarnishing of silver is a chemical change. It occurs when silver reacts with sulfur-containing substances in the air to form silver sulfide, which is the black tarnish seen on the surface of the metal. This change is irreversible and alters the composition of the silver.
Why is tarnish an example of chemical change?
Chemical Change duuh. Go to science class dumby.
Is the ability to tarnish a physical or chemical?
Chemical.
Why is it that The yolk of an egg which contains sulfur causes tarnish to form on silver is a physical or chemical change?
The tarnish that forms on silver due to sulfur in egg yolk represents a chemical change. This occurs because the sulfur reacts with silver to form silver sulfide, altering the chemical composition of the silver. Unlike physical changes, which do not change the substance's chemical identity, this reaction results in a new substance, indicating a chemical transformation.
Is a silver ring tarnishing a chemical change?
Yes, the tarnishing of a silver ring is a chemical change. It occurs when silver reacts with sulfur compounds in the air, forming silver sulfide, which appears as a black tarnish. This process alters the chemical composition of the silver, making it a distinct chemical change rather than a physical one. Once tarnished, the original properties of the silver cannot be restored without a chemical reaction to remove the tarnish.
Is salt and vinegar removing tarnish from a penny physical or a chemical change?
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.
