Silver sulfide (Ag2S) is the common tarnish on silver objects. What weight of silver sulfide can be made from 1.23 mg of hydrogen sulfide (H2S) obtained from a rotten egg? The reaction of formation of silver sulfide is given below:
Ag(s) + H2S(g) + O2(g)® Ag2S(s) + H2O(l) (Equation must first be balanced.)
