Question

A) S → SO2, →? - NaHSO3, → Na2So3Дополните пожалуйста

Answer 1

S→SO2→H2SO3→NaHSO3→Na2SO3

Answer 2

A) S → SO2 → NaHSO3 → Na2SO3

To complete the given sequence, we can add the following step:

S → SO2 → NaHSO3 → Na2SO3 → Na2S

The addition of Na2S represents the conversion of Na2SO3 to Na2S. This reaction can occur through the reduction of sodium sulfite (Na2SO3) using a reducing agent such as sulfur or sodium borohydride. The reaction can be represented as follows:

Na2SO3 + 2H2S → Na2S + 3H2O + SO2

So, the completed sequence would be:

S → SO2 → NaHSO3 → Na2SO3 → Na2S
