Question

question 20 of 30
what allows electrons to flow between electrodes in an electrochemical cell?
a. salt bridge
b. conducting wire
c. battery
d. electrolyte solutions

Explanation:

In an electrochemical cell, electrons flow from the anode to the cathode through an external circuit. The conducting wire provides a pathway for the electrons to move between the electrodes. A salt - bridge maintains electrical neutrality by allowing the flow of ions, a battery is a type of electrochemical cell, and electrolyte solutions contain ions that participate in redox reactions but do not directly allow electron flow between electrodes.

Answer:

B. Conducting wire
