1) S + Hg → HgS (compound reaction; sulfur, mercury sulfide);
2) 2HgS + 3O2 → 2SO2 ↑ + 2HgO (substitution reaction; mercury sulfide, oxygen, sulfur (IV) oxide, mercury oxide);
3) SO2 + 2NaOH → Na2SO3 + H2O (exchange reaction; sulfur (IV) oxide, sodium hydroxide, sodium sulfite, water);
4) Na2SO3 + 2HCl → SO2 ↑ + 2NaCl + H2O (exchange reaction; sodium sulfite, hydrochloric acid, sulfur (IV) oxide, sodium chloride, water);
5) 2SO2 + O2 → 2SO3 (compound reaction; sulfur (IV) oxide, oxygen, sulfur (VI) oxide);
6) SO3 + H2O → H2SO4 (compound reaction; sulfur (VI) oxide, water, sulfuric acid).
