Question 5 options: The cell potential for an electrochemical cell with a Zn, Zn2 half-cell and an Al, Al3 half-cell is V. Enter your answer to the hundredths place and do not leave out a leading zero, if it is needed.

The voltage is  

Explanation:

Generally the half reaction for Zn, Zn2 half-cell is mathematically represented as

      ⇔      (reference study academy)

and the electric potential for this is a constant value

Generally the half reaction for Al, Al3 half-cell is mathematically represented as

       ⇔  

and the electric potential for this is constant value  

Therefore the cell potential for an electrochemical cell  is mathematically represented as

substituting values
