Multiple Choice

Which of the following equations represents the roasting of lead(II) sulfide ore?

A) PbS(s) + 4H₂O(l) → Pb(OH) ₃^-(aq) + H₂S(aq) + H₃O⁺(aq)
B) PbS(s) + H₂(g) → Pb(s) + H₂S(g)
C) 2PbS(s) + C(s) → 2Pb(s) + CS₂(l)
D) PbS(s) + 2H₂O(l) → Pb(OH) ₂(s) + H₂S(aq)
E) 2PbS(s) + 3O₂(g) → 2PbO(s) + 2SO₂(g)
