Identify the chemical equation given: 2H₂ + O₂ → 2H₂O.
Understand that reactants are the substances that start a chemical reaction, and they are found on the left side of the equation.
Recognize that products are the substances formed as a result of the chemical reaction, and they are found on the right side of the equation.
In the equation 2H₂ + O₂ → 2H₂O, the reactants are H₂ and O₂ because they are on the left side of the arrow.
The product in this reaction is H₂O, as it is on the right side of the arrow.
