Homework Statement
For a cell in which the reaction Zn(s)+ Ni^2+(aq)->Ni(s)+ Zn^2+(aq) calculate the E(cell) when [Ni^2+]=0.05M, [Zn^2+]=0.85M.
Then, find the ratio of [Ni^2+]/[Zn^2+], when the cell is "flat"

I know that volatility is more or less proportionally related to vapor pressure.
If they are directly related, are they any exceptions where a more volatile substance may have a higher boiling point than a less volatile substance?

Okay I found out that the real volume is indeed less than the ideal volume, but I don't get how the real volume is bigger than the ideal volume? I thought it would be the other way around because molecular volume becomes significant at high pressures meaning that gases have less free space to...
At first I thought an induced ion dipole only applied to non-polar molecules, but in the textbook it says it polar molecules are affected by induced ion-dipole forces as well ("for the polar molecule, it enhances the dipole moment already present", Silberberg) ? If that's so, does that mean that...
1. Consider the quadratic equation ax^2+px+aq+q=0 where a does not equal to zero & p and q are constants . It is known that one of the roots of the quadratic equation is always 1 regardless of the value of a. Prove that p+q=0
