Multiple Choice
A voltaic cell is prepared in which aluminum metal is oxidized to Al3+, and nickel(II) is reduced to nickel metal. Which of the following represents the correctly balanced equation for this reaction?
A) Al(s) + Ni2+(aq) → Al3+(aq) + Ni(s)
B) Al(s) + 2Ni2+(aq) → Al3+(aq) + 2Ni(s)
C) 2Al(s) + 3Ni2+(aq) → 2Al3+(aq) + 3Ni(s)
D) Al3+(aq) + 2Ni(s) → Al(s) + 2Ni2+(aq)
E) 2Al3+(aq) + 3Ni(s) → 2Al(s) + 3Ni2+(aq)
