Question

Cadmium and zinc are used in a cell to produce cadmium metal. Using the standard reduction potentials shown, calculate the cell potential and identify the type of cell.
Cd2+(aq) + 2e– Cd(s) Eº = –0.40 V
Zn2+(aq) + 2e– Zn(s) Eº = –0.76 V

A. +0.36 V; galvanic
B. –0.36 V; electrolytic
C. –1.16 V; electrolytic
D. +1.16 V; galvanic

Answer 1

@Jesstho.-. help!

Answer 2

@aaronq

Answer 3

first write the equation, then use: \(\large \sf E_{Cell}=E^{cathode}-E^{anode}\)

Answer 4

so the answer would be C?

Answer 5

nope

Answer 6

oh... so it's B! thank you! :)

Answer 7

it's A

Answer 8
