Rust on an artifact is an example of chemical decomposition.
Rust on an artifact is an example of chemical decomposition.
Explanation: Rust is a reddish-brown compound called iron oxide that forms when iron reacts with oxygen in the presence of water or moisture. This process is known as oxidation. When iron is exposed to air and moisture, the iron atoms react with oxygen atoms to form iron oxide molecules, which results in the formation of rust. This is a chemical reaction where the iron undergoes a change in its chemical composition, leading to the decomposition of the iron into iron oxide. Therefore, rust on an artifact is an example of chemical decomposition.
