    The minimum number of moles O2 needed is 0.50 moles (option B)

    Explanation:

    Step 1: Data given

    Number of moles CO2 produced = 1.0 moles

    Step 2: The balanced equation

    2 CO + O2 → 2CO2

    Step 3: Calculate moles of O2

    For 2 moles CO we need 1 mol O2 to produce 2 moles CO2

    For 1.0 mol CO2 produced, we need 1.0 / 2 = 0.50 moles O2

    The minimum number of moles O2 needed is 0.50 moles (option B)
