Balance the equation;
___Mg+__HCI->__MgCI2+__H2
How many moles of hydrogen gas are produced when 3.0 molesbof magnesium react?

  • CHEM! (SCIENCE) NEED HELP -

    when you balance it...and it is very easy...
    Mg+2HCl>>MgCl2 + H2

    you see that for each mole of Mg, you get one mole of H2. So for three moles of Mg, you get....
