Chemistry Problem: Obtaining Ag(2)S from 19.00g Ag, @.80 H(2)S & 1.600g O(2)

[tommyjohn]

Homework Statement

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.

Homework Equations

I am completely lost and have no idea how to even start this equation, I need some hekp thanks

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?
