The problem of 1eV There's a place I don't understand. Please answer it 1 Coulomb= 6.28*10^18 electrons 1J =1w *1 s =1A*1V*1s =1C*1V = 6.28*10^18 eV It's my derivation, but it's in the book 1J= 1/1.609*10^18 [eV]=6.215*10^18[eV] Please explain where I was wrong and how I got this in the book

The derivation is completely correct, just the last step. 1C should be equal to 1 / 1.609 * 10 ^ (- 19) elementary charges, or 1 / 1.6 * 10 ^ (- 19) elementary charges. Your calculation is wrong

Does electrochemistry have anything to do with Volt's invention of battery

It's about you
The point is that the principle is exactly the same

Volta, the Italian physicist and inventor of battery, died?

In 1827,

What's the difference between a voltaic stack and a voltaic battery?

Volta invented a device that can stably supply flowing electric charge. This is a battery made of copper and zinc plates, namely voltaic battery, the predecessor of dry battery
