Correct! The substances that undergo a chemical change are called the reactants, and the new substances formed in a chemical reaction are called the products.

To figure this out on your own, you can follow these steps:

1. Review the definition of a chemical reaction: A chemical reaction is a process that leads to the transformation of a set of chemical substances into another set of substances.
2. Understand that reactants are the substances present at the beginning of a chemical reaction. They are the ones that react and undergo a chemical change.
3. Recognize that products are the substances formed as a result of the chemical reaction. These are the new substances that did not exist before the reaction took place.
4. Remember that in a balanced chemical equation, reactants are typically written on the left side, and products are written on the right side.

By understanding these concepts and steps, you can easily identify the reactants and products in a chemical reaction.
