An example of a chemical change is the reaction between sodium and water to produce sodium hydroxide and hydrogen.
What are the 4 chemical changes?
Rotting, burning, cooking, and rusting are all further types of chemical changes because they produce substances that are entirely new chemical compounds. For example, burned wood becomes ash, carbon dioxide, and water. When exposed to water, iron becomes a mixture of several hydrated iron oxides and hydroxides.
