The Nernst Equation- I apologize in advance for my ignorance

AI Thread Summary
The discussion revolves around understanding the Nernst Equation, specifically in the context of a copper-aluminum cell with a negative E cell value of -1.33. Participants clarify that E0 represents the standard cell potential, and the number of electrons exchanged (n) is crucial for calculations, typically found in the half-reaction equations. The pH and ion concentration can be incorporated into the equation by adjusting the reaction quotient (Q), which is calculated based on the concentrations of reactants and products. The gas constant R is confirmed as 8.31 J/(mol·K), and temperature should be in Kelvin, but it is not squared in the equation. Overall, the thread emphasizes the need for clear definitions and step-by-step guidance in applying the Nernst Equation.

Ecell = E0cell - (RT/nF)lnQ
So I understand the Nernst Equation, but I don't have some info. (Please bare with me, I'm in secondary)
I'm doing a Cu - Al cell. My E cell is negative (-1.33). Does this have an affect on the equation?
What exactly does E0 stand for? I understand how to find E cell, but do I square it by something? I can't find online how many electrons are swapped. How many electrons are swapped?
How do you factor in the pH? I've calculated the pH and the number of ions in it, but where do i add this in on the equation? Please lay it out how you would in the equation so I can see
I'm stuck on R (gas constant, which is 8.31 (volt-coulomb)/(mol-K)). I can't figure out the volt-coulomb as i don't know the voltage. How can I calculate the coulomb? Then the volt-coulomb? And is Mol-K (Mole)(Kelvin)? If so, do I factor in the temperature in Kelvins twice?
For N (n = number of moles of electrons exchanged in the electrochemical reaction) do i just multiply the moles per electron?
Finally - What exactly am I dividing to calculate Q? (How do I calculate Q?)

Please explain this all in basic jargon - or just normal English if you prefer. My vocabulary is limited. Thank you!

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
