Chemical, it is reacting with the air
Tarnishing of metal is a chemical change because it involves a reaction between the metal and substances in the environment (such as oxygen or sulfur compounds) that forms a new compound on the surface of the metal, altering its properties.
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.

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.
Tarnishing is a process where a metal (like silver or copper) loses its shine and develops a dull or darkened appearance due to exposure to air, moisture, or chemicals. It is caused by a chemical reaction that forms a thin layer of corrosion on the metal surface.
The color change on metal caused by a chemical change is called tarnishing. Tarnishing can result from exposure to elements such as oxygen, sulfur, or other chemicals, leading to discoloration or darkening of the metal surface.
Tarnishing of costume jewelry is a chemical change. It occurs when the metal in the jewelry reacts with substances in the air, like oxygen or sulfur compounds, forming a new compound on the surface of the metal that gives it a dull or dark appearance.

Yes, tarnishing of a spoon is a chemical change. It occurs when the metal reacts with substances in the environment (such as oxygen or sulfur) to form a new compound, which results in a change in the appearance and properties of the spoon.
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 where the metal's surface reacts with oxygen and other compounds in the environment, forming a new substance that alters the metal's appearance.

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.
The best way to clean earrings with out tarnishing the metal is by using rubbing alcohol. This will not only clean the earrings, but it also works as a disinfectant. Rubbing alcohol does all this without tarnishing the metal.
Oil protects metal from tarnishing by forming a barrier that prevents moisture and oxygen from reaching the surface. This barrier reduces the likelihood of chemical reactions that lead to oxidation and corrosion, which are the primary causes of tarnishing. Additionally, the oil can help repel contaminants and pollutants that might otherwise contribute to the tarnishing process, thereby prolonging the metal's appearance and integrity.
It is a chemical change.
chemical, because when a penny is tarnished its a chemical change because, its weathered down its destroyed. The tarnish itself is usually either the oxide and/or sulfide of the underlying metal.
