Write the reaction equations of the transformation scheme in molecular and ionic form: S-K2S-H2S-SO2-SO3
| May 20, 2021 | education
Having compiled the equations corresponding to the chain of transformations, having written them in molecular and ionic form, we get the following:
S → K2S → H2S → SO2 → SO3
1) 2K + S = K2S;
2) K2S + 2HCl= 2KCl + H2S↑;
2K+ + S2- + 2H+ + 2Cl– = 2K+ + 2Cl– + H2S↑;
S2- + 2H+ = H2S.
3) 2H2S + 3O2 = 2SO2 + 2H2O;
4) 2SO2 + O2 = 2SO3.
