WebA chemical change always produces one or more types of matter that differ from the matter present before the change. The formation of rust is a chemical change because rust is a different kind of matter than the iron, oxygen, and water present before the rust formed. WebJan 26, 2024 · The reddish colour on the metal is called rusting of iron. When iron metal is exposed to air for a long time, it oxidises and forms a reddish-brown colour iron oxide on its surface. This red-brown substance is known as rust, and the process of forming rust is known as rusting.The iron rusting formula is 4Fe + 3O2 + 6H2O → 4Fe (OH)3.
