What is the voltage of a galvanic cell made with zinc (Zn) and aluminum (AI)? A. 0.92 V B. -0.92 V
c. -2.44 V
D. 2.44 V​

The correct option is (a) "0.92 V".

Explanation:

The voltage of a galvanic cell made with zinc (Zn) and aluminum (AI) is given by :

Voltage =Ered- Eoxd

Where

Ered = reduction potential

Eoxd = oxidation potential

As per reduction standard potentials, the emf of Zinc is -0.76 V  and the emf of Aluminium is -1.66 V. So,

V = 0.76 - (-1.66)

= 0.9 V

Hence, the correct option is (a) "0.92 V".

the answer is c. nacl

c. electrical charges of ionic bonds.
