Is there a limitation on how much the VSEPR model can tell us and what's the molecular orbital theory?

Taylor 1F

To identify poyldentate type molecules are N and O- the only indicators of bonding areas. Are there more?

Taylor 1F

The molecules ability to fully give off a proton is limited, therefore the reaction is reversible. While, a strong base fully gives off its proton and is fully ionized.

Taylor 1F

First I think you have to find molarity with your new liters and you can use the same moles. Then after finding molarity use the the second Ka to find the pH of the resulting solution

Taylor 1F

The acid of a compound in Bronsted's definition:is the proton giver. While the base of the compound the proton acceptor. But most compounds are consistent so you just have to know that carbonic acid is an acid and like NH3 is usually a base.

Taylor 1F

Usually the Roman numeral is placed after the metal, which is specifying the charge of the particular metal. So, most of the time the Roman numeral is in the middle of the compound name, but I don't think there's particular reason for putting it after.

Taylor 1F

We have to memorize them, but we only need to know like common ones(i.e numbers 1-8 prefixes)

Taylor 1F

In order to find bond angles you have to have an idea of whether there's lone pairs or whether an element will have more electronegativity. So you don't have to draw lewis structure as long as you have an idea of what the bond relationships are.

Taylor 1F

you have to draw each lewis structure, then if any have an odd electron number it's a radical, and then look at the structures and rank them in increasing bong angles

Taylor 1F

Since the Fluorine is so electronegative compared to Boron so it attracts the electrons. Also BF3 comes out to a formal charge of 0 which makes it acceptable for Boron not to have a complete octet

Taylor 1F

You use the periodic table, but if there's a discrepancy you could use other factors like the electron configuration and it's atomic radius

Taylor 1F

For your first question, Silver is 4d^10 5s^1 because this allows the atomic sub shells to be more stable since the d block is filled and the valence of electron (5s^1) is easily attainable

Taylor 1F

Also what is the difference between the Hund's principle and Pauli Exclusion principle and how does it effect e- configuration?

Taylor 1F

How does adding on the nodes change the shape of the atom exactly?

Taylor 1F

As the electron moves from different orbitals, it absorbs energy . However, these sub-level energy aren't dependent of proximity to nucleus it holds a different energy threshold while changing the shape of the atom.

Taylor 1F

Also, are we supposed to do the pre-modules for week 2 before next week?

Taylor 1F

Is an aqueous solution still considered a liquid?
