Sadly yes lol

Resonance Structures are basically just a set that compares and contrasts two or more Lewis Structures that represent a molecule.

Emily Mendez 4C

Yes we will

Emily Mendez 4C

Does anyone know when midterm grades will be released?

Emily Mendez 4C

My TA notified me today that dipoles will be on the test

Emily Mendez 4C

Hello everyone! Just wanted to wish everyone a good luck on their midterm tomorrow! Don't forget your bruin card or your scientific calculator because my TA told me they will be checking and making sure that everyone has a scientific calculator.

Silicon nitride Si3N4, a material used for spinal fusion devices is made by reacting Si and Nitrogen gas (N2) at high temperatures. How much Si (in grams) is needed to react with an excess of N2 to prepare 120g of Si3N4 if the precent yield for the reaction is 100%. Can someone show their calculatio...

Emily Mendez 4C

It will cover bond lengths and energies

Emily Mendez 4C

Can someone tell me where I can access the worksheet that the midterm review session TAs were going over?

Emily Mendez 4C

the midterm will cover fundaments, quantum, and some early chemical bond material. Don't forget to bring your bruin Id that day.

Emily Mendez 4C

Hi guys, I didn't go to lecture yesterday, but Lavelle sent out an email that said that he was going to mention when the other review sessions were going to take place. Can someone comment down below when the rest of the review sessions would be. thank you!

Emily Mendez 4C

Did anyone go to the midterm review session for fundamentals yesterday? I couldn't attend that one. If someone went, can you do me a huge favor and post what the TA talked about?

Emily Mendez 4C

What is the best way to study for the midterm?

Emily Mendez 4C

Hey guys! Does anyone know if we will be given a worksheet with all the formulas once again like they provided with Test 1 for the midterm?

Emily Mendez 4C

Yes!! Professor Lavelle sent out an email saying that he will anounce when the midterm reviews will be tomorrow in class.

Emily Mendez 4C

Hello Everyone! Has Professor Lavelle said anything about having midterm reviews for chemistry anytime soon?

Emily Mendez 4C

The sections that you can do for homework are either the Quantum World or Chemical Bonds

Emily Mendez 4C

Pick any 5 questions you would like to do from any section of the "Quantum World"

Emily Mendez 4C

I don't know the format of the midterm, but I'm pretty sure it will be like Test 1 where you have to show your calculations. I know for a fact it will be longer than Test 1 since it is a midterm and it will cover what we are learning in Quantum and what we are learned in the beginning.

Emily Mendez 4C

I think it will mostly be calculations because going off test 1, it was mostly calculations and response questions.

Emily Mendez 4C

If professor Lavelle mentioned it in his lecture then we should know electromagnetic spectrum.

Emily Mendez 4C

My TA said that the equations will always be provided for the tests but I'm not sure if for the midterms and final exams it will be the same.

Emily Mendez 4C

Does anyone know when Professor Lavelle will update our grades for the class? Or our TA?

Emily Mendez 4C

I'm not sure when everyone will get there tests back, but I hope it's this week in our discussion sections because I'm anxious to know what I got. You could ask your TA !

Emily Mendez 4C

You don't need a blue book for this chemistry class.

Emily Mendez 4C

He hasn't really specified if he wants a certain format, but he has told us to know about sig figs and scientific notation.

Emily Mendez 4C

I don't think that you will need your bruin card for the tests that will be given in discussion sections, but you will for sure need it for midterms and the final exam. For the tests in discussion. just to play it safe, have your ID number memorized and you should be good to go. Good luck to you all!

Emily Mendez 4C

It is most likely that molarity and dilution will be on the test since he covered a good amount of material on those topics on lecture. Maybe he didn’t talk about them as much in the module but it will definitely be on the test and well better to be prepared than not prepared!

Emily Mendez 4C

A chemical equation always has to be balanced. In order for the whole chemical equation to be balanced when their is a fraction involved, you have to multiply the entire equation by the smallest factor to get all the whole numbers. Whole numbers are essential since it will make it easier for chemist...

Emily Mendez 4C

Yes you are correct. Whole numbers make the equation seem a little more sophisticated and easier for chemists to read. Just make sure to multiply both sides of the equation which won't affect the balance if each atom type.

Emily Mendez 4C

I'm having trouble on solving a question on the pre-assessment module. I don't know if anyone can help me out on what are the steps I'm suppose to take to solve it. I would really appreciate it. I'm completely confused. During a summer camping weekend 4 moles of butane (C4H10) gas were used for cook...

Emily Mendez 4C

I hadn't seen this post so I was about to ask a question related to yours, but thank you so much for clarifying things!

Emily Mendez 4C

In all the empirical & molecular formulas questions in the homework, am I allowed to round? I see that if I round for example the moles of a certain element I get another answer than when I don't round. Can someone just notify me when its okay to round and when I shouldn't round.
