Answer 2

Answer:

*If you heat an iron bar until it glows red hot, it is still chemically the same iron. The iron has not changed into something else. ... Examples of chemical changes would be the reaction of iron with air (rusting} or the reaction of a metal and acid. Certain observations will indicate that a chemical change has occurred.
