Re: least covalent character
Hey, The least covalent character is the most ionic one. The most ionic character is in the compound in which the atoms have bigger electronegativity difference. F is the most electronegative element in the Periodic Chart, which makes it, most of the time, part of the most ionic compounds. Thus, tho...

Re: hw 12.117
Because the equation HNO_{2}_{(aq)}+NH_{3}_{(aq)}\rightleftharpoons NH_{4}^{+}_{(aq)}+NO_{2}^{-} contains the equation H_{2}O \rightleftharpoons O^{2-}+2H^{+} . Thus, in this case, since the water equation is the net ionic equation, the equilibrium constant should be referrin...

Re: Weak Bases
Hey! So, it has to do with the equilibrium constants. You see, molecules in a solution are constantly dissociating and reprotonating, and the relative stability of the acid and conjugate base, represented by equilibrium constants, determines the rate of the forward and backward reactions, right? So,...

Re: Polar/Nonpolar Covalent bonds vs. Ionic bonds
Hey! Exactly, because any difference between electronegativities indicates that the bond is not 100% covalent.

Re: Electron configurations
Hey!
Since Cl is in the third period, it can have an extended octet. Therefore, the electron that goes over the octet goes to the 3d orbital. Does that make sense?

Re: Resonance [ENDORSED]
Hey! So resonance is as if the double bond kept switching from one pair of atoms to another. This constant "switching" is created by the fact that the electron are not stuck between only one pair of the molecules atoms, but rather changes between other pairs as well. "Different equiva...
