Tarnishing of silver is caused by small amounts of hydrogen sulfide released into the atmosphere by decaying organic material and volcanic activity. According to the following equation:
4Ag(s) + 2H2S(g) + O2(g) → 2Ag2S(s) + 2H2(l)
How many grams of Ag2S can be produced from 1.70g H2S if sufficient amount of the other reactants are present?
The molar masses are:
Answer: 12.4 g
