Silver tarnishes in the presence of hydrogen sulfide (which smells like rotten eggs) and oxygen because of the following unbalanced chemical reaction
Ag + H2S + O2 à Ag2S + H2O
How many grams of silver sulfide can be formed from 1.1 g Ag reacting with 1.7 g of H2S and 1.9 g of O2
4Ag + 2H2S + O2 = 2Ag2S + 2H2O
x=0.005
