Write the reaction equation: S — SO2 — SO3 — Na2SO4 — BaSO4 Na — Na2O — NaOH — NaNO3

Transformations in the first chain of equations can be performed using the following reactions:
1. S + O2 = SO2;
2. SO2 + O2 = SO3;
3. SO3 + 2NaOH = Na2SO4 + H2O;
4. Na2SO4 + Ba (NO3) 2 = BaSO4 + 2NaNO3.
To solve the second chain of transformations, we will use the reaction equations:
1. 4Na + O2 = 2Na2O;
2. Na2O + H2O = 2NaOH;
3. NaOH + HNO3 = NaNO3 + H2O.
