  • Q:

    Iron (relative atomic mass = 56) and sulfur (relative atomic mass = 32) can react in multiple ways to make various forms of iron (II) sulfur. Among the possible reactions is:

    8Fe + S8 → 8FeS

    Suppose 7 g of iron reacted with 4 g of sulfur in the reaction above. Which of the following statements would be true?


     

    A

    Fe is the limiting reagent

    B

    S8 is the limiting reagent

    C

    FeS is the limiting reagent

    D

    There is no limiting reagent
