Question 9 of 10 What are the half-reactions for a galvanic cell with Zn and Ni electrodes?
A. Zn2+(aq) + 2e → Zn(s) and Ni2+(aq) + 2e → Ni(s)
B. Zn2+(aq) + 2e → Zn(s) and Ni(s) + Ni2+(aq) + 2e
C. Zn(s) → Zn2+(aq) + 2e and Ni(s) → Ni2+(aq) + 2e
O D. Zn(s) → Zn2+(aq) + 2e and Ni2+(aq) + 2e → Ni(s)
SUBMIT

D. Zn(s) → Zn2+(aq) + 2e and Ni2+(aq) + 2e → Ni(s)

Explanation:

I also just took the A P E X quiz and it was correct

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )

catya that's not even a b or c
