What are the word equation for the reaction that causes potassium to tarnish?
The word equation for the reaction that causes potassium to tarnish is: potassium (K) + oxygen (O2) → potassium oxide (K2O).
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.
Is the ability to tarnish a physical or chemical property?
The ability to tarnish is a chemical property. Tarnishing occurs when a substance undergoes a chemical reaction with other compounds in its environment, leading to the formation of a different substance on its surface.
Is silver tarnishing a physical or 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.
Is tarnishing silver a chemical change?
Tarnish on silver is Silver Oxide, which is oxidised silver. This is indeed a chemical reaction.
Is tarnish of silver physical or chemical change?

How can you tarnish a penny?
One way to tarnish a penny is by exposing it to a mixture of salt and vinegar. This combination creates a chemical reaction that causes the copper surface of the penny to darken and tarnish over time.
What happens to silver if you leave it out?
If you leave silver out in the open air, it will eventually tarnish due to a chemical reaction with sulfur compounds in the environment. This tarnish can be removed through polishing. To prevent tarnishing, silver can be stored properly in airtight containers or with anti-tarnish materials.
Is the ability to tarnish a physical or chemical?
Chemical.
