The conjugate base is more stable due to resonance and electron withdrawing properties of oxygen.

The locations are listed on his website under Final Rooms and review sessions on the right hand side.

I believe it will always be 2 unless a specific spin number is included or if a principle/rule is violated.

The concentration of the two relevant groups (reactants and products) still remain the same before and after the addition of the inert gas, so the reaction would proceed as it would either way.

Yes, it is the number of bonds attached to the central atom, but only referring to the ligands (ignore cations/anions).

James Nguyen 3G

I believe the denticity just refers to how many times the ligand can bond to the transition metal. However, they generally do donate all of these electrons.

James Nguyen 3G

Ligand refers to the atom or molecule that binds to the central metal atom. When Ammonia forms part of a coordination compound with a transition metal, such as Iron, Ammonia is considered a ligand.

James Nguyen 3G

The pi bond is created by the overlap between the orbitals that are brought together by the sigma bond.

James Nguyen 3G

Lone pairs repel regions of electron density in different ways than bonds do in that they repel them more than bonds do, so they push out more and change the angle that would be there if it were all bonds.

James Nguyen 3G

The more electronegative atom should generally have the negative charge if there is one, and the less electronegative atom should generally have the positive charge if there is one.

James Nguyen 3G

A polar bond is when the bond is not quite ionic but the difference in electronegativity is still signifucant, such as a difference of 1.0. A nonpolar bond is when the electronegativities are more similar, such as between Carbon and Hydrogen.

James Nguyen 3G

All Ionic bonds have covalent character because there is still attraction between the cation and the electrons that the anion contains, which causes a 'distortion' of the electrons, which is similar to a covalent bond and creates covalent character depending on the level of distortion.

James Nguyen 3G

When the formal charges are zero and the more electronegative / higher Ionization energy atoms are charged if the whole molecule has a charge.

James Nguyen 3G

The lowest energy structure will generally have the lowest possible formal charges and also preferably have all the atoms contain octets.

James Nguyen 3G

Two electrons generally have to be opposite spins to be paired in an orbital. The numbers are different depending on the direction they spin (counterclockwise, clockwise)

James Nguyen 3G

It determines the shape of the orbit in which the electron resides, but there is no way to determine exactly where in this orbit the electron is, rather we can predict the region it is generally restricted to.

James Nguyen 3G

I believe that you would use the equation K = 1/2mv^2 to find kinetic energy, using delta v and the mass of an electron then multiply this by avogadro's constant.

James Nguyen 3G

Are we expected to understand this concept for the upcoming test? As in sulfides, chlorides, etc.

Technically, Alcohol is a solution
