Multiple Choice

Which of the following is the overall reaction for the formation of rust?

A) 2MnO₂(s) + 2NH₄Cl(aq) + Zn(s) → Mn₂O₃(s) + Zn(NH₃) ₂Cl₂(s) + H₂O(l)
B) Cd(s) +2NiO(OH) (s) +2H₂O(l) →Cd(OH) ₂(s) +2Ni(OH) ₂(s)
C) 4Fe²⁺(aq) + O₂(g) + (2 + 4x) H₂O → 2Fe₂O₃·xH₂O + 4H⁺(aq)
D) Zn(s) + 2MnO₂(s) →ZnO(s) +Mn₂O₃(s)
E) 2Zn(s) + O₂(g) +4H⁺(aq) →2Zn²⁺(aq) +2H₂O(l)
