Tarnishing silverware is a chemical change. It occurs when silver atoms react with sulfur compounds in the air or on the surface of the silverware, forming silver sulfide. This chemical reaction changes the composition of the silverware, making it appear tarnished.
The tarnishing of a silver surface is a chemical change. This is because the silver undergoes a reaction with sulfur compounds in the air, forming silver sulfide. This chemical reaction results in a change in the composition and properties of the silver surface.
The tarnishing of silver when exposed to air for several weeks is a chemical change. This is because the silver reacts with sulfur compounds present in the air to form silver sulfide, which creates the tarnished appearance on the surface of the utensils.
Casting silver in a mold is a reversible physical change because the silver can be melted again and reshaped into a different form. The process does not alter the chemical composition of the silver.
Tarnishing of a silver fork in air is a chemical change because it involves a reaction between the silver and sulfur-containing compounds in the air to form silver sulfide. This reaction alters the chemical composition of the silver on the surface of the fork, resulting in the formation of a dull, tarnished layer.

Silver tarnishing is a chemical change. It occurs when silver reacts with sulfur compounds in the air to form a layer of silver sulfide on the surface. This chemical reaction changes the composition of the silver, resulting in the tarnished appearance.
Yes. Tarnished silver is caused by the reaction of the silver with oxygen.
chemical, e.g. if you have silver, and it tarnishes, the dark spots (the tarnished areas) are actually silver oxide. If it were a physical change, the silver would need to change states of matter. Into gas, liquid or plasma
Tarnished silver is a chemical compound. When silver reacts with sulfur and oxygen in the air, it forms silver sulfide, which gives silver items a tarnished appearance. This compound is not easily removed by physical means and requires chemical cleaning to restore the silver's luster.

The tarnishing of a silver surface is a chemical change. This is because the silver undergoes a reaction with sulfur compounds in the air, forming silver sulfide. This chemical reaction results in a change in the composition and properties of the silver surface.
A chemical property. the tarnished surface is chemically altered to a new compound (silver oxide).
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.
Yes, tarnishing of silver objects is a physical property because it involves a change in the appearance of the silver due to the interaction with air and other substances, without changing the composition of the silver itself.
