    Answer:

    This reaction has infinite ways to be balanced

    Explanation:

    To balance this equation we can use the algebraic method:

    N2O4(g) + CO → NO(g) + CO2(g)+NO2(g)

    Where we write each molecule as a letter:

    A + B → C + D + E

    Then, we write the equations according the number of atoms of each molecule. That is:

    Oxygen → 4A + B = C + 2D + 2E (1)

    Nitrogen → 2A = C + E (2)

    Carbon → B = D (3)

    Then, we have to give 1 arbitral number for a letter. For example:

    B = 1; D = 1

    (1) 4A + 1 = C + 2 + 2E

    4A = C + 2E + 1

    2A = C + E (2) Twice (2):

    4A = 2C + 2E

    Subtracting (1) in (2)

    C + 2E + 1 = 2C + 2E

    C + 1 = 2C

    1 = C

    Si 1 = C:

    4A + 1 = 1 + 2 + 2E

    4A = 2 + 2E (1)

    y:

    2A = 1 + E (2)

    Twice:

    4A = 2 + 2E

    As (1) and (2) are the same equation:

    This reaction has infinite ways to be balanced

    For example:

    N2O4(g) + CO → NO(g) + CO2(g)+NO2(g)
