When iron metal reacts with oxygen, the reaction can form Fe2O3. Write a balanced chemical equation for this reaction, and find the number of moles of oxygen that are needed to form 6 mol of Fe2O3. Show your work.

  • physical science -

    you need 3 O for 2 Fe
    ___O is diatomic

    4 Fe + 3 O2 --> 2 Fe2O3


    3 moles of O2 for 2 moles of Fe2O3

    so you need 3 times as much for 6 moles
