    Reactants: Ethanol (C₅H₅OH), Oxygen (O₂)

    Products: Carbon dioxide (CO₂) and Water (H₂O)

    Explanation:

    Let's rewrite each part of the described situation in chemical equation terms.

    Ethanol - C₂H₅OH

    is burned in the prescence of - +

    oxygen - O₂

    producing - →

    carbon dioxide - CO₂

    and - +

    water - H₂O

    Chemical equation:

    C₂H₅OH + O₂ → CO₂ + H₂O

    The terms on the left side of a chemical equation are reactants, and the terms on the right side of a chemical equation are products.

    Therefore, since we know this, ethanol (C₂H₅OH) & oxygen (O₂) are the reactants, and carbon dioxide (CO₂) & water (H₂O) are the products.
