Re: sp2 hybridization

the p orbital is not empty but rather it is combined with the s orbital to create an intermediate sp orbital. I hope this helps

Re: Single arrow vs. double arrows

theoretically, it is still an equilibrium reaction so the double arrows are present, but because it is a strong acid there will be full dissociation. Maybe the solutions manual made a mistake? it has been known to happen.

Re: the effect of expansion on a system

the expansion means volume is increasing, which in turn means that pressure is decreasing. I think that the reaction would then shift to the side with the less pressure in order to create that equilibrium then. I hope this helps!

in my opinion, it would be a good idea to have the most common strong and weak acids/bases memorized, but i'm not sure if its mandatory

Q=K is perfectly equilibrium, but this is very rare and you will not come across it very often, if at all

Re: more on determining polydentate

I think that when it asks for number of bonds a ligand could make, you list all possibilities, but it could be possible for it to not donate all of its electrons all the time. Just my thoughts though

Re: Cations

actually, the -ate is added when the oxidation state of the metal is positive, not negative. when the oxidation state of the metal is negative, there is no addition of suffixes.

Re: Naming Coordination Compounds

i think that the -o at the end of the ligands is just how you write them, i do not know if there is an actual reason, but for the second part of your question, yes ammonia and chloride are both ligands for that coordination compound.

Re: Pi Bonds

There can only be one sigma bond, because only one s orbital can be hybridized with multiple p orbitals, therefore, a double sigma bond cannot occur because two s orbitals are nowhere near each other and also cannot hybridize together.

Re: atomic structure of HOCO

i think the way that the molecule is written is indicative of the way that the elements are bonded and structured. that is why it is not written as CHO2. that is why the H is bonded to the O and not to the C. The C also is the radical this structure.

Re: Electronegativity and electron affinity

Both electronegativity and electron affinity are quite similar and have the same trend. electronegativity is the strength of attracting electrons while electron affinity is the heat released when an electron is added.

Re: Bond Strength

I am not sure what exactly you are referring to, but longer bonds are weaker and shorter bonds are stronger. That is why molecules with double bonds (shorter) are stronger than those with single bonds and thus have higher dissociation energies! Yay!

Re: Formal charge and most electronegative element

When you draw Lewis structures, the most stable form would have 0 formal charges. Sometimes, you might run into structures that have unavoidable formal charges. In these cases, there is a preference for the more electronegative atom to carry the negative formal charge, and it is more stable for the ...

Yes, that is correct. -Ate have three oxygens and -ite is just one less with the two exceptions that you mentioned.

Re: Chemical Bonds Lewis Structure: Octet Rule Violation [ENDORSED]

It is probably an octet violator because of the effective charge of the chlorine. It is probably more stable with the odd number of electrons.

i know this topic isn't going to be on the test, but the question is

what is the minimum uncertainty in the speed of an electron confined to within a lead atom of diameter 350. pm? model the atom as a one-dimensional box with a length equal to the diameter of the actual atom.
