We get the following reaction equations:

1) Na2S + H2SO4 → SO2 + H2S + Na2SO4 (exchange reaction);

2) SO2 → S + O2 (compound reaction; at a temperature of 2500 ºС);

3) S + O2 → SO2 (decomposition reaction);

4) SO2 + H2O → H2SO3 (compound reaction);

5) H2SO3 + 2NaCl → 2HCl + Na2SO3 (exchange reaction).
