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.

It's a chemical change. A thin layer of silver on the surface reacts with oxygen in the air - to form silver oxide.
Reinforced silverplate is a type of silver plating that involves a thicker layer of silver applied to a base metal, typically through electroplating. This process enhances the durability and longevity of the silver coating, making it more resistant to wear and tarnishing compared to standard silverplate. Often used for flatware and decorative items, reinforced silverplate is designed to withstand regular use while maintaining its aesthetic appeal.
Zeisel's method is used to estimate the alkoxy linkages in an organic compound. In this method the organic compound containing alkoxy group is treated with hydrogen iodide and the alkyl halide formed is further treated with silver nitrate to precipitate silver iodide In this reaction only hydrogen iodide can be used because it consists of an ionic bond, while HF, HCl, HBr contain covalent bond where an iodide ion is liberated which forms a precipitate with silver nitrate. The silver iodide can be weighed and from its weight the number or alkoxy group can be estimated.
Silver invented Post-It Notes. He was trained as a chemist.
Silver platter tarnishing is a chemical change: 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.
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.

Tarnish on silver is Silver Oxide, which is oxidised silver. This is indeed a chemical reaction.
Yes, silver tarnishing is a chemical change. It occurs when the silver reacts with sulfur compounds in the air to form silver sulfide, which gives silver a black or brownish tint. This chemical reaction cannot be easily reversed, unlike a physical change.
a physical property
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
