assume that 13.5g of AL react with HCl according to the following equation, at STP: Al(s) + HCl(aq) ---> AlCl3 + H2(g) Remember to balance the equation first.

a. how many moles of Al react?
b. how mang moles of H2 are produced?
c. how mang liters of H2 at STP are produced?


thank you :]

    C'mon. Get serious. If I don't know what you don't understand about this I can't help you. To start can you balance the equation? If so do so. If not why can't you. Go from there with the next thing you don't understand.

    actually i just need c

    In the future, if you will show what you can do and work through that, then ask your question, all of this preliminary stuff is not necessary.
    Remember that a mole of any (ideal) gas will occupy 22.4 L at STP.
    L H2 @ STP = mols H2 x 22.4 L/mol = ?.
