1) Na + O2 → Na2O (compound reaction; sodium, oxygen, sodium oxide);
2) Na2O + SO2 → Na2SO3 (compound reaction; sodium oxide, sulfur (IV) oxide, sodium sulfite);
3) Na2SO3 → Na2O + SO2 (decomposition reaction; sodium sulfite, sodium oxide, sulfur (IV) oxide);
4) Na2O + H2O → 2NaOH (compound reaction; sodium oxide, water, sodium hydroxide).
