Which reaction gives a product that is an atmospheric pollutant causing acid rain?

A3Mg(s) + SO2(g) → MgS(s) + 2MgO(s)

B(NH4)2SO4(s) + Ca(OH)2(s) → 2NH3(g) + CaSO4(s) + 2H2O(l)

C2MnO4⁻(aq) + 5SO2(g) + 2H2O(l) → 2Mn²⁺(aq) + 4H⁺(aq) + 5SO4²⁻(aq)

D2FeSO4(s) → Fe2O3(s) + SO2(g) + SO3(g)

✓ Correct answer

D: 2FeSO4(s) → Fe2O3(s) + SO2(g) + SO3(g)
