Question 1

Which energy conversion shown below takes place in a galvanic cell?

◦ electrical to chemical
◦ chemical to electrical
◦ mechanical to chemical
◦ chemical to mechanical
◦ mechanical to electrical

Question 2

Which metal, Al or Ni could reduce Zn²⁺ to Zn(s) if placed in a Zn²⁺(aq) solution?

	Zn²⁺ + 2e^–→ Zn		E° = –0.76 V
	Al³⁺ + 3e^–→ Al		E° = –1.66 V

Ni²⁺ + 2e^–→ Ni

E° = –0.23 V

◦ Al
◦ Ni
◦ Both Al and Ni would work.
◦ Neither Al nor Ni would work.
◦ Additional information is needed.
