Answer: electrons transferred.
- A ions in solution
- B electrons transferred
- C protons released
- D molecules reacting
Correct answer: B. electrons transferred
Explanation: n is the number of moles of electrons transferred in the balanced cell reaction.
In a Daniell cell, electrons flow externally from the zinc anode (oxidation) through the voltmeter to the copper cathode (reduction), while the salt bridge completes the circuit.
