A chemical change by definition involves a reaction that rearranges the atoms of one or more substances, resulting in a change in their chemical properties or “make-up,” forming at least one NEW substance. From your own experience, what is one thing that you observed that underwent a change chemically? Explain why it would be classified under chemical change.

Explanation:

Rust used to be a very common reaction. Iron was used in autos and they formed oxides of iron or rust as the auto or truck aged. You can still see this in older vehicles, especially those used in the country.

To make wine from grapes, the grapes need to ferment which is a process where the grape just changes to alcohol or sometimes vinegar, depending on how the grapes ferment. You can certainly tell the difference between grape juice, wine an vinegar when you taste them. A chemical reaction has taken place.

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.
