Question

You find a nail on the ground in the parking lot, in a small puddle of water. Rust has formed on the outside of the nail. Was this a physical or chemical change? Explain

Answer 1

Something with rust means that it has oxidized which is a chemical change. The reason it is a chemical change is because the iron had a chemical reaction with the oxygen and water which resulted in the creation of a new compound (that is a chemical change). You can't change the nail to not having any rust form because the rust will still exist ( If you clean it the rust will still be there but on another object )

Answer 2

Rusting of Iron nail is a type of chemical Change.

What is Chemical Change ?
