It is a physical change. This is so because no new substance is formed. Hydrogen Sulfide is Hydrogen Sulfide wether it is boiling, at room temperature, or freezing.
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.
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.
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.
Silver platter tarnishing is a chemical change: a reaction with hydrogen sulfide.
The chemical equation Mg + H2S -> MgS + H2.
It is a chemical process - a reaction with hydrogen sulfide.
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.
The chemical formula for hydrogen sulfide is H2S.
