Draw a diagram depicting what happens to the atoms of elements or molecules of compounds when a chemical change occurs and when a physical change occurs. Explain how the changes differ.

Whereas there are some outward signs of a chemical change, many of these can be mimicked by physical changes. What are some more reliable ways by which a chemical change can be distinguished from a physical change?
