Hello,
I'm not very sure but I think the correct answer is D) Water Wave
I really hope this helps!!!! Happy Holidays!!!! (:
C. pain reliever
ex. tylenol, aleve, etc.
From the reduction standard potentials;
The emf of Zinc = -0.76 V
and the emf of Aluminium = -1.66 V
In a galvanic cell the component with lower standard reduction potential gets oxidized and that it is added to the anode compartment.
Therefore. the voltage of a galvanic cell made with zinc and aluminium will be;
Voltage =Ered- Eoxd
= -0.76 - (-1.66)
= 0.9 V
