That statement is backwards! Chemical reactions don't make new materials called reactants. Here's how it works:

* Reactants: These are the starting materials in a chemical reaction. They are the substances that will undergo a change.

* Products: These are the new substances formed as a result of the chemical reaction. They are the result of the reactants changing.

Think of it like baking a cake:

* Reactants: Flour, sugar, eggs, butter, etc.

* Products: The delicious cake!

The chemical reaction (baking) transforms the reactants into a new product.
