Either is fine but you should know how to identify both of them.

204765696

Yes that is correct. Dipole moments refer to the polarization of the electrons in a bond.

204765696

I'm not sure, but just to be safe we should

204765696

Yes but I don't think we have to draw them. I think we just need to know how to identify and describe them.

204765696

You use the one with formal charges closest to 0.

It depends on the element. To calculate bond order in chemistry, subtract the number of the electrons in the anti-bonding molecules from the number of electrons in the bonding molecules. Then, divide the result by 2. The higher the bond order, the more stable the molecule.

The sigma and pi bonds tells us the strength of the interactions and the behavior of the molecules.

204765696

To identify bond angles and shape, locate the central atom and see how many bonds are connected to it. You also have to count the lone pairs as bonds. If the number of bonds is 2, the shape is linear and angles are 180 degrees. If the number of bonds is 3, then the shape is triagonal planar and angl...

No they're also determined by the number of bonds and the number of lone pairs on the central atom. The lone pairs are important because it makes the shape of the molecule.

204765696

All molecules with four bonding pairs and no lone pairs are tetrahedral

204765696

No the order doesn't matter!

204765696

If the atom has more than three valence electrons in its outer shell, three of the electron orbitals hybridize and one of the p orbitals remains unhybridized. It is the unhybridized p orbitals that then form pi bonds for double bonding. Just as with the sp2 hybrids, the unhybridized electrons can th...

These two opposite ions attract each other and form the ionic bond. Covalent bonding is a form of chemical bonding between two non metallic atoms which is characterized by the sharing of pairs of electrons between atoms and other covalent bonds

204765696

Nonpolar covalent bonds are a type of chemical bond where two atoms share a pair of electrons with each other. Polar covalent bonding is a type of chemical bond where a pair of electrons is unequally shared between two atoms.

204765696

It can be for many reasons, however one of the common mistakes are placing parantheses in the right places. You should check that!

204765696

It's the emission of electrons from a material due to the shining of a light

204765696

Only if the particle has mass, it cannot be faster than the speed of light

204765696

The orbitals s, p, d, f have different shapes and sizes

204765696

I think it doesn't hurt to read the textbook reading even if we don't have to cause it might be helpful for other concepts we need to know!

204765696

Yes! It's any 7 problems you want to do from outline 2!

I'm not sure how grading works for Professor Lavelle, but I feel like it would be fair to give us partial credit instead of zero points especially if our answer was only off a couple decimal points. As long as we showed our work and put effort in, I think we'll be fine.

1 mol vs 1 mmol is that 1 mmol is equivalent to 10^-3 mol.

Significant figures are not affected by constants. The important rule is to have the same amount of significant figures in your answer and in the value given in the original problem.
