true

false

​

Answer 1

The potential difference between the terminals of a cell is caused by chemical reactions inside the cell.

This statement is true.

Explanation:

• The potential difference between the terminals of a cell is caused by chemical reactions inside the cell.
• When a chemical reaction takes place inside a cell the electrons flow from anode to cathode.
• This happens when the battery is connected to a source of current.  
• Battery supplies voltage in the form of electromotive force.
• The overall reaction inside the battery is a redox reaction.
