A chemical reaction is when energy is released or absorbed. Also an example of a chemical reaction is a base and an acid. When an acid hits a base it makes salt and water. Reversible reactions are ones where the reaction can be paralleled to have the substance come back to its original state. A chemical reaction is also irreversible, because you can't get the original substance back. E.g: If you bake a cake with milk, flour and sugar and you mix it all together after you have baked it you can't get each substance back therefore it is irreversible and is a Chemical Reaction
