We are given a chain of transformations from sulfur to tetravalent sulfur oxide. In order to implement it, we need to carry out three chemical reactions.

The first is the production of tetravalent sulfur oxide, for this we carry out the reaction of sulfur and oxygen, the combustion of sulfur.

S + O2 = SO2

Further, from the resulting reaction product of tetravalent sulfur oxide, we need to obtain a sodium sulfide salt. To obtain it, add bivalent sodium oxide to sulfur oxide. The molecular equation of the reaction can be written as follows:

SO2 + Na2O = Na2SO3

The reaction of the decomposition of a salt of sulfur sulfide to sodium oxide and tetravalent sulfur oxide.

Na2SO3 = Na2O + SO2.
