Some examples are wood burning, fireworks exploding, spoon tarnishing, and egg frying. These are all chemical reactions because you can never bring them back to their original state.

If you cannot separate two substances from each other it is a chemical change. If it changes color, tempeture, odor, formation of bubbles or solid, it is a chemical change.

Be careful, just because it has one of these properties, doesn't mean its a chemical change. Some substances that have one of these properties can be a physical change.

Some signs of a chemical change are production of odor, production of bubbles, change in color, formation of a solid and change in temperature. However, there are some exceptions. If something had the sign before you made a mixture, it is not a chemical change. Usually, you will need to see 2 or more signs to have evidence of a chemical change.
