Answer 2

Chemical Reaction Chain:

The given chemical reaction chain can be solved step by step as follows:

1. S + MgS: - When sulfur (S) reacts with magnesium sulfide (MgS), it forms magnesium disulfide (MgS2).

2. MgS2 + SO2: - When magnesium disulfide (MgS2) reacts with sulfur dioxide (SO2), it forms magnesium sulfite (MgSO3).

3. MgSO3 + Na2SO3: - When magnesium sulfite (MgSO3) reacts with sodium sulfite (Na2SO3), it forms sodium magnesium sulfite (Na2Mg(SO3)2).

4. Na2Mg(SO3)2 + Na2SO4: - When sodium magnesium sulfite (Na2Mg(SO3)2) reacts with sodium sulfate (Na2SO4), it forms sodium magnesium sulfate (Na2Mg(SO4)2).

5. Na2Mg(SO4)2 + PbSO4: - When sodium magnesium sulfate (Na2Mg(SO4)2) reacts with lead(II) sulfate (PbSO4), it forms sodium sulfate (Na2SO4) and lead(II) magnesium sulfate (PbMg(SO4)2).

The final chemical reaction chain is as follows: S + MgS → MgS2 + SO2 → MgSO3 + Na2SO3 → Na2Mg(SO3)2 + Na2SO4 → Na2Mg(SO4)2 + PbSO4
