1) Name THREE personalities' (philosophers and/or scientists) who conceived ideas about atoms. (2) List TWO discoveries which led to inventions that helped later scientists to see atoms.
(3) Mention ONE thing that amazes you about how we 'see' atoms.

The free energy change, ΔG, is negative for the voltaic cell.

Explanation:

One major difference between an electrolytic cell and a voltaic cell is that a voltaic cell produces energy from a spontaneous chemical process while an electrolytic del! Produces energy from a non spontaneous chemical process.

Given a spontaneous chemical process, ∆G is always negative as in a voltaic cell. How ever, in a non spontaneous electrolytic cell, ∆G is positive.

This is the major difference between a voltaic cell or and an electrolytic cell.
