• D

Galvanic (voltaic) cells convert

• mechanical energy in to electrical energy

• potential energy in to electrical energy

• electrical energy in to chemical energy

• chemical energy in to electrical energy

What is a redox reaction?

• A reaction where both reactants get reduced.

• A reaction where both reactants get oxidized.

• A reaction that involves a transfer of electrons between reactants.

• A reaction that involves the combustion of at least one reactant.

What is reduction?

• It is the gain of electrons.

• It is the loss of electrons.

• It is the creation of electrons.

• It is the destruction of electrons.

What is oxidation?

• It is the gain of electrons.

• It is the loss of electrons.

• It is the creation of electrons.

• It is the destruction of electrons.

What is an anode?

• It is the electrode where oxidation takes place.

• It is the electrode where reduction takes place.

• It is an aqueous solution containing an electrode.

• It is the salt bridge that connects half-cells.

What is a cathode?

• It is the electrode where oxidation takes place.

• It is the electrode where reduction takes place.

• It is an aqueous solution containing an electrode.

• It is the salt bridge that connects half-cells.

Electrons always flow from

• cathode to anode

• anode to cathode

Oxidation occurs at the
