Moving down a group there is an increase in the number of valence shells = higher shielding effect. This means that the valence e-s feel a weaker pull from the nucleus and can easily dissociate = stronger acid

105002507

You should use water as another product and fill in the reactants after

105002507

the larger the atomic radius indicates a longer bond and stronger acid

105002507

Yes, acids and bases can neutralize each other.

105002507

It is important to know that a base is an e- donor!!

105002507

The higher the electronegativity difference, the stronger the acid

105002507

HI would be the stronger acid

105002507

I'm pretty sure ligands are named alphabetically

105002507

The unique rate depends on the stoichiometric coefficient & stays the same for all products and reactants

105002507

Lewis acid: e- acceptor
Lewis base: e- donor

Bronsted acid: proton donor
Bronsted base: proton acceptor

105002507

no, degrees are not an si unit. Si unit would be a radian

105002507

A just stands for the central atom!

105002507

Yes because the lone pairs push down on the rest of the bonds and affect the degree of angle

105002507

P is the least electronegative in comparison and therefore is the central atom. It also has the ability to be an expanded octet

105002507

Do dipoles matter when drawing lewis structures?

105002507

The bond lengths are still the same probably because of resonance. All bond lengths are the same even though they are single or double because resonances are hybrids

105002507

Can elements only be isoelectronic if they have the same # of valence electrons?

105002507

I think formal charge is more important (with 0 being the most stable) because there are expections for certain elements regarding the octet rule

105002507

Does the formula...

FC = group # - (bonds + nonbinding e-)

work the same as the one presented in lecture? This formula makes more sense to me and seems to result in all the same results.

105002507

whats the maximum number of different ways to write a lewis structure?

105002507

I thought phosphorus had 5 valence electrons?

105002507

I am confused on why the electron configuration of Cu is not [Ar]4s^2 3d^9. this is question 3.5 6th edition

105002507

what does ionization energy mean?

105002507

E is the energy of one photon, v is frequency, and h is plank's constant

105002507

what units do we use for each of the constants/ variables?

105002507

When do we use kg?

105002507

well everything uses kg even though molar mass is given in g per mole. it makes it easier to write out

105002507

The uncertainty principle has two complementary variables for which there is a limit to the precision with which we can measure either. Essentially, there's the uncertainty in momentum and the uncertainty in position of a particle. These variables represent the precision to which either the momentum...

Thank you very much!! These worksheets are extremely helpful

105002507

It is because EMR consists of particles of energy called photos and each of those photos has a fixed energy of hV. This is according to Einstein.
