Answer:
The cell reaction reaches equilibrium quickly and the cell emf becomes zero.
Explanation:
The purpose of a salt bridge is not to move electrons from the electrolyte, its main function is to maintain charge balance because the electrons are moving from one-half cell to the other.
A solution of a salt that dissociates easily is normally used. Water is ineffective at functioning as a salt bridge. Hence the effect stated in the answer.
I think it is d because it talks about other things the other ones finest talk about so go with d or c I hope you get it right good luck
Answer:
Chemical Change
Explanation:
chemical bonds within the substance have been altered because a new substance has been produced. It cannot be a mixture because they do not involve changes in matter, it cannot be a physical change because they do not result in new substances, it is not a solution because those do not involve changes in matter.
Answer:
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
