    The answer to your question is C₂H₄ + 3O₂ ⇒ 2CO₂ + 2H₂O

    Explanation:

    Data

    Ethylene = C₂H₄

    Oxygen = O₂

    Carbon dioxide = CO₂

    Water = H₂O

    Reaction

    C₂H₄ + O₂ ⇒ CO₂ + H₂O

    Reactant Element Product

    2 Carbon 1

    4 Hydrogen 2

    2 Oxygen 3

    This reaction is unbalanced

    C₂H₄ + 3O₂ ⇒ 2CO₂ + 2H₂O

    Reactant Element Product

    2 Carbon 2

    4 Hydrogen 4

    2 Oxygen 6

    Now, the reaction is balanced
