Nitrogen and sulfur — practice question

Which reaction produces a product that is an atmospheric pollutant responsible for acid rain?

  • A$3\text{Mg}(s) + \text{SO}_2(g) \rightarrow \text{MgS}(s) + 2\text{MgO}(s)$
  • B$(\text{NH}_4)_2\text{SO}_4(s) + \text{Ca(OH)}_2(s) \rightarrow 2\text{NH}_3(g) + \text{CaSO}_4(s) + 2\text{H}_2\text{O}(l)$
  • C$2\text{MnO}_4^-(aq) + 5\text{SO}_2(g) + 2\text{H}_2\text{O}(l) \rightarrow 2\text{Mn}^{2+}(aq) + 4\text{H}^+(aq) + 5\text{SO}_4^{2-}(aq)$
  • D$2\text{FeSO}_4(s) \rightarrow \text{Fe}_2\text{O}_3(s) + \text{SO}_2(g) + \text{SO}_3(g)$
