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

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
