How do you complete the circuit when using 2 half-cells?

• acid bridge

• base bridge

• salt bridge

If a half-cell does not involve metal atoms or ions, what can you use to complete the circuit?

• Carbon nanotube

• Carbon rod

• Diamonds

Different pairs of metals produce different voltages.

• True

• False

The circuit must be complete for the electrons to flow.

• True

• False

The closer the elements in the Electrochemical Series, the greater the voltage produced.

• True

• False

Electrons will flow from the element higher in the Electrochemical Series to the one lower in the Electrochemical Series.
