Would H3PO4 or HClO4 be the stronger acid in part D of 6C.19?

curry 1E

Since this is a neutralization problem, your products are water and whatever they give you; now, you need to figure out what its reactants are from those. So, for A, you see that KBr and H2O are the products. So, the reactants must be KOH (base) and HBr (acid). This combination of H+ ions and OH- i...

Which would be the stronger acid HClO or HClO2? I know that you first look at bond length and then anion strength but how would you figure this one out?

curry 1E

When determining the strength of acid between two compounds, do you first look at bond length or anion strength or both? This is in regards to question 6C.19. Thanks!

curry 1E

What does resonance have to do with acid strength? Thanks

What would be the bronsted base in homework question 6A.5? Would it be HPO42-?

curry 1E

How would you make CH3COOH a conjugate base? I know you have to remove a H+ but do you remove it from the H3 or the H at the end?

curry 1E

I get that for a conjugate acid you add an H and add + to overall charge. But, for part a), would you add the H to the H of CH3 or the H of NH2?

curry 1E

Thank you guys that makes so much more sense!

Why is it K3 and Br3 and not just K and Br?

Can someone help me with 9C.1 part D? how do you know charge of SO4?

This is all very helpful thank you so much

What are some examples of neutral ligands?

What is an anionic ligand and what does it have to do with naming?

On the final how will we be asked to name compounds? Will we be given the formula first?

In general, why do d-block elements behave differently than main-group elements?

curry 1E

Thank you so much this was actually really helpful.

Exactly what about the bronsted acids and bases are we expected to know besides naming them?

Can someone please help me with this one?

Which one would have the strongest interaction? I have seen it answered both ways and I am confused.

curry 1E

What are the sigma and Pi bonds of SO2?

curry 1E

Hello I am still very confused on hybridization. How do we derive the hybridization by looking at the lewis structure? Or do we have to look at each valence shell of each atom?

curry 1E

I am still a little confused on boiling point and how you would tell the higher one when given two polar molecules

curry 1E

I think we should just know between two molecules with different interactions, we should be able to dictate which molecule will have the higher boiling and melting point. Typically, it will be the molecule with the stronger interactions that will have higher boiling and melting points. I understand...

Why is the ion-ion interaction the strongest interaction?

It should most likely include concepts pertaining to molecular shape and structure as well as those slides regarding dipole-dipole interactions, hydrogen bonds, covalent bonds, and ionic bonds that were covered by Dr. Lavelle on the last slide on the Friday before the midterm exam. I missed lecture...

curry 1E

Are ion-dipole moments stronger than dipole dipole moments?

curry 1E

Yes, I agree with everyone above, we do not really have to worry about dashes and wedges on the test

curry 1E

Why are dipole-dipole moments weaker as the molecules move farther apart?

What type of questions on test 2 will we see on this subject?

I am having a hard time understanding bond lengths and what constitutes a bond having a longer or shorter length than one another. Thanks!

I am still confused with polarizing power, can someone help me put these in increasing power Rb+, Be2+, Sr2+

For this question can someone explain to me what polarizing power is? Thank you

"Select from each of the following pairs of Lewis structures the one that is likely to make the dominant contribution to a reso-nance hybrid. Explain your selection. "

How do I figure this one out?

For this question, I get how to do formal charge, but how do you determine which one is lower energy structure? Is it just the one with the lowest charges that are closest to 0?

18. For the following reaction if 1.00 x 102 g H2O reacts with 1.00 x 102 g CaC2 identify the limiting reactant.

CaC2(s) + H2O(l) ---> Ca(OH)2(aq) + C2H2(g)

I understand that you need to balance the equation first, then find the molar mass. But then what do you do after that?
