Answer :
The answer is (1) electrical energy, spontaneously.
Voltaic (or galvanic) cells involve coupled oxidation and reduction reactions that spontaneously generate electromotive force.
Answer:
(1) electrical energy, spontaneously
Explanation:
Voltaic cells or galvanic cells are electrochemical systems in which electrical energy is produced through spontaneous chemical reactions. Redox (reduction-oxidation reactions) processes forms the basis of voltaic cells.
Oxidation which involves loss of electrons takes place at the anode. These electrons move to the positive cathode where reduction or the gain of electrons takes place. The movement of electrons from the anode to the cathode generates electrical energy. Thus, chemical is spontaneously converted to electrical energy.
