Ah I see, thank you.

Sorry about that, let me try again. Besides the obvious spacing issues I incorrectly mention Sodium Nitrate when it really should be Sodium Nitrite. At first the pH of the undisturbed weak acid HN02 is around .69. I found it using a simple ICE table and the initial concentration HN02 (.200...

What amount of sodium Nitrate must be added to 500 ml of .200 M solution of HN02. Ka=4.0^-4 Ka=(H+)(A-) -------- (HA) Ph of 5 = 1.0^-5 (H+) so, (1.0^-5)(x) ---------- = 4.0^-4 , however X turns out to be way too big...

Just to clarify what I did, it's basically Coulomb's law for nuclear repulsion+ Coulomb's law for electron repulsion = Coulomb's law for electron - proton attraction ( I multiplied this by two because the proton of hydrogen 1 is attracted to the electron of hydrogen 2 and the electron of...

If the bond length of two atoms is the distance where the force of repulsion is equal to the force of attraction, then one could figure out what the bond length of H2 is by setting the net force of attraction to the net force of repulsion and solving for distance. However when I try this ...

How does forming a bond between two ions lower the overall energy of the system? Also how would two hydrogen atoms form if there is proton-proton repulsion and electron-electron repulsion and only proton-electron attraction?
