The products of the electrolysis of molten MgBr₂ are:
A) H₂(g) and O₂(g)
B) H₂(g) and Br₂(g)
C) Mg(l) and O₂(g)
D) Mg(l) and Br₂(g)

Right now I understand it to be that electrolysis of aqueous MgBr₂, since it includes H₂O, produces H₂(g) and O₂(g). But since it's molten MgBr₂, then water can't be involved, so I think it's D) Mg(l) and Br₂(g). The answer key says that the answer's C though, but how can O₂(g) be produced if there's no water?

D it is.
