Maddie

does this have to do with determining the strength of the acid

Maddie

produces B12

Maddie

why is it that sometimes in coordination compounds it is just iron and other times it is written as ferrate

Maddie

Can it ever result in both just more of one than the other

Maddie

I struggled with the iron and cyanide one just because i did not memorize it. I also struggled with the magnesium problem

Maddie

Can amphiprotic be applied to lewis acids and bases

Maddie

Does he place a lot of emphasis on the difference or will he take both

Maddie

i thought they have to form a ring

Maddie

it transfers oxygen via myoglobins

Maddie

doesnt it depend on whether or not they are giving up or accepting a proton

Maddie

so is it usually the charge found for the transition metal

Maddie

Thank you, this helped a lot with my questions on ligands.

Maddie

So does it mainly depend on what is written on each side of the equation?

Maddie

Thank you, these responses helped to clarify alot

Maddie

Its also always important to remember that sometimes even if it looks symmetrical, such as with tetrahedrals, you still need to look at the dipole moments to determine polarity.

Maddie

Yes almost every time there is a lone pair on the model the angle will slightly diminish.

Maddie

Does it have anything to do with transition metals?

Maddie

The main Latin version of the name is not necessary to know

Maddie

pi bons are intramolecular forces that resttricts rotation where as hydrogen bonding in an intermolecular force

Maddie

Will he give us the actual electronegativity values on the tests though?

Maddie

This might be controversial and I don't think anyone has addressed it yet but I believe hydrogen bonding can only happen with NItrogen, Oxygen, and Fluorine.

Maddie

making flashcards based off one of the charts was very helpful for me.

Maddie

This is not related but does anyone know where to find intermolecular problems in the book?

Maddie

Thank you, that makes more sense.

Maddie

Also if it being an incomplete octet doesn't necessarily mean it is a radical then what is the determining factor

Maddie

How does the fromal charge determine whih one is radical?

Maddie

So just to clarify, memorizing these specific ions is not something that we should place at the forefront when studying for this midterm?

Maddie

why is a smaller atomic radius make it more polarizable

Maddie

If it is on the midterm I don't think it will ask you to do it very many times

Maddie

Thank you, this was a helpful clarification

Maddie

This is helpful when dealing with cations and. anions to know where to pull electrons from

Maddie

I would also note to be mindful of this exception especially when writing the electron configuration for Cu and Cr

Maddie

What is the difference between electrnegativity and electron affinity?

Maddie

I believe you just have to continue testing it to see which one results in the smallest formal charge

Maddie

How do you determine what charge the direction goes in when drawing lewis structures?

Maddie

You should work on the topic of the week but throwing in past problems that you are still confused on wouldn't hurt!

Maddie

For this class, I don't believe that sig figs are very important. My TA said that both him and Lavelle will not be looking that closely at the answers

Maddie

yeah that's right:)

Maddie

It also doesn't matter when your drawing out the configuration as long as you're consistent whether or not you have them spinning down or up every time

Maddie

you can tell by using the formal charge of an atom or reconfiguring the lewis structure if you do not have enough electrons to fully complete the lewis structure.

Maddie

I think the most useful way to study is to first complete the modules and then work on the homework problems that go over the questions you encountered throughout the module.

Maddie

usually I convert it to meters as a default

Maddie

I found the modules to be most useful for studying

Maddie

This topic is explored more in physics based courses so you don't have to focus on it much as of now.

Maddie

It only works for real particles

Maddie

I was told that you don't have to pay too close attention to the sig figs so as long as you don't round with every step you should be fine.

Maddie

what color was the hydro flask?

Maddie

Is this for when you're finding the empirical formula or just converting grams to moles?

Maddie

I find a few things helpful when it comes to easing some test anxieties. Getting exercise in any form whether it be doing a quick set of jumping jacks or going on a run is usually really helpful in calming me down. I also like to rewrite my notes and make sure I understand everything very clearly as...

Maddie

Thank you so much for sharing your experiences in order to better prepare us for what the future and specifically med school has in store!
