Nitrogen can't have more than an octet

Madeline Marron 1I

I found it easier to just memorize the list of strong acids and bases

Madeline Marron 1I

Not necessarily a joke, more of a play on words. In any case, Happy Holidays y'all

Madeline Marron 1I

I'm good, I'm going to decorate Christmas cookies tonight which is exciting!

Madeline Marron 1I

I think they will be updating it on Thursday

Madeline Marron 1I

since the speed of light is a constant (c) it will always be the same number

Madeline Marron 1I

That was also something I was running into, I figured that the website was under maintenance or something

Madeline Marron 1I

This was super duper helpful, thank you guys!

Madeline Marron 1I

I'm definitely going to as many review sessions as possible and reviewing the homework problems from the textbook since most/all of the questions on the final will be from there

Madeline Marron 1I

Mine wasn't working earlier today either but it is working now

Madeline Marron 1I

yeah I couldn't tell either!

Madeline Marron 1I

carbon can't have more than an octet so you take one of the hydrogens and attach it to the oxygen

Madeline Marron 1I

My mom and I like to make raspberry pie, its dank

Madeline Marron 1I

single bond is sigma, double bond is one sigma and one pi, a triple is one sigma and two pi bonds

Madeline Marron 1I

So this isn't a TV show but I just watched "I, Tonya" and it was super good, but I just gotta say how much I hate her ex husband. So triggered, I can't even right now.

Madeline Marron 1I

I check on CCLE, you can scroll to the very bottom and on the left will be a grades tab

Madeline Marron 1I

there is a high possibility we will be having a lecture that day

Madeline Marron 1I

whichever has the lowest formal charge is the one that would be the most stable

Madeline Marron 1I

It's because F is the most electronegative and since there are two you would see it pulling as a net force

Madeline Marron 1I

As a political science major who took this class for funzies i'm having mad regrets. It's funny enough because essentially everyone in my immediate/extended family are scientists/doctors but I guess I was just built different

Madeline Marron 1I

I think someone also said this but i ran Cross Country in high school so I would get mad anxiety before my races and what helped me was just realizing that I had put in the work and worrying about it was only making myself go through unnecessary pain(obviously just telling yourself you are fine wont...

Madeline Marron 1I

I've read over my notes but I still don't quite understand what m(sub)l and m(sub)s are, as well as how you figure out what they are for each specific orbital. If anyone has any knowledge on this I would greatly appreciate any help!

Madeline Marron 1I

not only are there 4 hydrogen atoms, there are also 4 lone pairs between the nitrogen and the oxygen. these act as receptors of hydrogen atoms that are bonded to F, O, N. meaning there would be 8 possible hydrogen bond points

Madeline Marron 1I

because they are created as molecules move around, and since the dipole that is created is not permanent that means it is easily broken

Madeline Marron 1I

yes! the VSEPR model can be used to measure polarity

Madeline Marron 1I

yes , as well as everything in the "chemical bonds" outline

Madeline Marron 1I

I recognize some of the material for sure but there certainly are instances where i'd never encountered topics before. My high school didn't offer AP chemistry either.

Madeline Marron 1I

Not stellar because I took this class for funzies but the way things are looking I might get a B, which is a dreadful thought. But i'm willing to stay optimistic because you can do anything if you set your mind to it.

Madeline Marron 1I

My all time favorite show is Bobs Burgers, it's animated but also witty. I also have recently gotten into Naruto. I know that sounds kinda whack but surprisingly its really good, and has an insane amount of episodes to you'll always have another episode to watch. I actually just spent almost 11 hour...

Madeline Marron 1I

I'm planning on going to a lot more step up sessions as well as doing more homework problems, because Lavelle said that some of the problems on the midterm were taken from the homework.

Madeline Marron 1I

I was having trouble with this one as well but I finally figured out it was due to the fact that I was not converting Angstroms correctly. Also make sure to be particular about how you enter equations such as this one into your calculator, because I got a few wrong answers since I was typing it in w...

Madeline Marron 1I

I dressed up as Louise Belcher and watched some scary movies with some close friends! It was my first time watching The Nightmare Before Christmas, super good.

Madeline Marron 1I

I was curious about this as well, I emailed my TA but he has not responded yet, but I can imagine a good amount of students did have had technical problems which will delay the scores from getting released.

Madeline Marron 1I

The ones that will be correct should essentially be a never ending series. So if you get to the end and you can immediately start where the beginning of the wave starts then you will be good.

Madeline Marron 1I

When i write them down I deliberately make v=frequency as like a cursive looking one and the velocity in my own handwriting. The best way to know is on the equation sheet is just to remember which equation uses which. Most of the time it will be for frequency, unless you're calculating momentum.

Madeline Marron 1I

We will be printing out the periodic table to use on the Midterm, as well as printing out the equations sheet so we won't have to memorize them.

Madeline Marron 1I

N2 ia the final while N1 is the initial

Madeline Marron 1I

That kept happening to me too all day. I think it's back up now, thankfully.

Madeline Marron 1I

Oh I hadn't thought of that, thank you!

Madeline Marron 1I

In today's lecture, for the second part of the worked examples, where did Dr. Lavelle get the mass from?

Madeline Marron 1I

Do we have to remember all of the equations and constants or will we be given an equation sheet to use during the midterm?

Madeline Marron 1I

Is it better convert the speed of light into nm before plugging it in, or waiting to convert the final answer?

Madeline Marron 1I

Highly recommend going to TA office hours if you are unsure of a concept or have any questions because it is better to be over prepared than under prepared!

Madeline Marron 1I

This answer was a little tricky for me as well because I wasn't familiar with the abbreviations for all the components, but thank you all for the help!

Madeline Marron 1I

I don't personally use an ipad because I prefer writing on paper, but my sister uses an ipad and she loves it. Although she is not a stem major but she recommends it to any one who asks. Also for the fatigued eyes I suggest getting blue light glasses to help keep your eyes from getting overworked.

Madeline Marron 1I

It took me an embarrassingly long time to figure out that I needed to capitalize my letting in order for the computer actually accept my answer.

Madeline Marron 1I

I'm pretty sure we can only gain a maximum of 5 points every week and those five posts are due every Sunday

Madeline Marron 1I

Thank you for explaining that "d" is density, that was giving me some trouble since I could not figure it out!

Madeline Marron 1I

I am also confused for the same reason as Alyssa, I'm unsure where to find the initial grams of both Hydrogen and Carbon.

Madeline Marron 1I

I understand how you're feeling in this situation since I haven't taken chemistry since my sophomore year of high school and I'm an incoming Freshman. All my friends told me I'm crazy for choosing to take Chemistry as one of my science requirements since I'm not a STEM major but I think it will be a...
