Homework Help: Chemistry problem

  1. Sep 12, 2009 #1
    1. The problem statement, all variables and given/known data

    silver tarnishes in the presence of hydrogen sulfide (rotten egg odor), also found in Chinese dry wall and oxygen because of the reaction:

    4Ag + 2H(2)S + O(2) --> 2Ag(2)S + 2H(2)O

    How many grams of Ag(2)S could be obtained from a mixture of 19.00g Ag, @.80 H(2)S and 1.600g O(2) and how many grams of the non-limiting reactants are left.

    2. Relevant equations
    Im completely lost and have no idea how to even start this equation, I need some hekp thanks

    3. The attempt at a solution
    Not sure

    This is a limiting reagent question, just there are three reagents to take into account.

    Ignore everything else for now - how many grams of H2S will react with 19.00g of Ag? Do you have that much H2S?
