PLEASE HELP ME ASAP Tell if Rusting (Oxidation) is a Physical or Chemical Change. Also, explain what it means and give an example. I WILL GIVE BRAINLIEST TO THE BEST ANSWER!!!

Redox reaction is the oxidation of iron, which forms iron oxide, also known as rust. This reaction can be symbolized with the following equation: 2Fe + 3O2 forms Fe2O3. Notice the iron atoms and oxygen molecules combine to form a new compound, which makes this reaction a chemical change.
