Question 1.
What is the main function of an electrochemical cell?
Show hintHide hint
Think about energy conversions involving batteries.
Question 2.
What is a galvanic cell?
Show hintHide hint
These cells power devices by harnessing chemical reactions.
3Question 3.
What is the major distinction between galvanic and electrolytic cells?
- Galvanic cells generate energy while electrolytic cells consume energy.
- Galvanic cells contain only inert substances.
- Electrolytic cells can't produce electricity.
