Chemical change occurs when one substance is transformed into one or more new products via a chemical reaction. Chemical changes are not reversible. We cannot bring back the original form of the substance.

Chemical change takes place through cooking, burning, rotting, spoiling or rusting.

Going back to the given situation above, the toasting of bread and for leaving it too long that the bread got burned is an example of chemical reaction.

The toaster adds heat energy to the bread for too long. The bread turns black and the texture changes. The toast is not the same substance as the bread. It cannot be changed back to bread.
