Ответ:
17. All of the above
18. hydrogen gas and oxygen gas
19. deposition of a metal layer on a material
Electrolytic cells use electric currents to drive a non-spontaneous reaction forward. This is also used in electroplating which involves the movement of metal cations to the surface of another metal. Water can also undergo electrochemical reactions by splitting it into its gaseous components, hydrogen and oxygen.
