because the iron and oxygen have combined on an atomic level creating the compound iron oxide and you would need to manipulate it on the atomic level to separate it.
There isn't really any such thing as an irreversible change, just changes that are so difficult they are unlikely to happen. It's a chemical change, because rust is a different substance from iron. If you put rust into a very hot furnace with carbon you can reduce it back to iron.
irreversible change
permanent- you are changing the chemicals in the iron when it rust

irreversible change.
Nail rusting is an irreversible change because it involves a chemical reaction where iron in the nail reacts with oxygen in the air to form iron oxide (rust). This process permanently alters the composition of the nail, making it difficult to reverse the formation of rust and return the nail to its original state without significant effort.
irreversible change is called a physical change.
Burning something is irreversible.
Yes, the rusting of a bicycle is a chemical change because it involves the oxidation of the iron in the metal to form iron oxide (rust), which is a different chemical compound than the original metal. This process is irreversible.
Yes, but it is so hard as not to be worth it.
Do you mean irreversible change? If so it means "It can not be changed".
Rust is a chemical change.
