You're going to be using the Nernst equation for this problem (E=E^*-RT/nFlnQ), but you have to do a few things first. R is 8.3145 J/mol*K and F is 96485 J/V*mol, with temp @ 298.15 K, those are your constants so you need to find the rest. To find Q, divide the [Products]/[Reactants]. You also need ...

Why is N2O an an exception to the symmetricalness around the central atom? It's the example in the textbook and wondering why a nitrogen is acting like the central atom. Thank you!

Re: Textbook 1.D 23 part c

This problem is more so asking for all possible outcomes for n=2, so it has the potential to fill 2s^2 and 2p^6 with the 2s-subshell (l=0,ml=1) and the 2p-subshell (l=1, ml=-1,0,+1 (3 spots)). I'm sorry it can be kind of confusing but I hope this helps!

Re: bond length

Hi!

So you would determine the bond length through the number of bonds (single bond being the longest and triple bond being the tightest) and the size of the atom. Hope this helps!
