Answer 6

In a chemical change, the atoms in the reactants rearrange themselves and bond together differently to form one or more new products with different characteristics than the reactants. When a new substance is formed, the change is called a chemical change. I agree with answer choices A and D, because steam and change in color isn't always a clue to a chemical reaction.
