<span>When the gases dihydrogen sulfide and oxygen react, they form the gases sulfur dioxide and water vapor. so the balanced equation is </span>2H2S(g) + 3O2(g) → 2SO2(g) + 2H2O(l) hope it helps
According to reaction , 2 moles of hydrogen sulfide reacts with 3 moles of oxygen gas to give to 2 moles of sulfur dioxide and 2 moles of water vapors.
