CHEMISTRY COMMUNITY

Malik Oda 1F

• Very few anions act as acids because it is more difficult for an anion to lose H+
• Exceptions are the anions: HSO4- and H2PO4-

The points above came from the notes. What are HSO4- and H2PO4- exceptions of and why are the considered exceptions?

Malik Oda 1F

Why don't Cl- and NaCl affect pH?

Malik Oda 1F

Amphoteric simply means that the ion is able to act as both an acid and a base.

Malik Oda 1F

I just got word that the final will be 8 questions like the midterm

Malik Oda 1F

I am also wondering about this because on the homework, some problems require us to know the names; however, I don't recall Dr. Lavelle mentioning anything about having to memorize the Latin names.

Malik Oda 1F

Working out really helps and being overconfident to keep a cool mind

Malik Oda 1F

I hear acids and bases is the hardest section. Is that due to memorization or math?

Malik Oda 1F

I briefly remember Dr. Lavelle going over this but I am not sure what was said about it. I don't think this is important to know.

Malik Oda 1F

Are chemistry community post points updated weekly or will they be added at once at the end of the semester?

Malik Oda 1F

Will we keep learning until the last lecture before the final or are we going to have a review lecture like for the midterm?

all I know is that it will be 3 hours, so one hour longer than the midterm

Malik Oda 1F

How many questions will the final be?

Malik Oda 1F

Just to make sure, the final is going to cover all topics we learned this quarter including high school review?

Malik Oda 1F

Do we have homework due for week 9?

Malik Oda 1F

What problems from the textbook cover the topics that will be on the test this week?

Malik Oda 1F

Where can I find the outline for test 2? Is it just outline 4?

Malik Oda 1F

I think it will only be on the ones taught in lecture and whatever Mondays lecture is about

Malik Oda 1F

Is the test more conceptual or math-based??

Malik Oda 1F

What are the topics I should be expecting on next week's test?

Malik Oda 1F

The last topic we covered was still on chemical bonds, so can I do my homework due tomorrow on chemical bonds still?

Malik Oda 1F

How do I identify an expanded octet and how would I approach drawing the Lewis Structure?

Malik Oda 1F

If I have an odd number of valence electrons how do I determine which molecule to put the extra electron onto? Would it be the most electronegative molecule?

Malik Oda 1F

In what situations is it ok to cancel out formal charges?

Malik Oda 1F

Can someone please clarify the concept of dipole moment and how to calculate it?

Malik Oda 1F

Is there an online version off the solution Manuel, like there is a textbook one?

Malik Oda 1F

Is the homework due this week focused only on chemical bonds or could it be can topic of midterm review?

Malik Oda 1F

Everything except the last slide Dr. Lavelle went over should be on the midterm I believe

Malik Oda 1F

Can you please post the work along with the the answers because it was hard to see all the work from the back of the lecture hall

Malik Oda 1F

Are chemistry community posts counted graded weekly or is it just required to have 50 by the end of the quarter?

Malik Oda 1F

Just a friendly reminder that if Sapling Learning isn't working for you, you can get your code traded in at the bookstore for free. The deadline is October 31st

Malik Oda 1F

My TA said that it might be incorporated into the problems but it won't be a separate problem. So a quantum problem might ask us to convert first before we can start solving using quantum methods.

Malik Oda 1F

Do we have access to the slides from in class?

Malik Oda 1F

I don't think there will be anymore modules. They were only there to help with material taught during weeks 1 and 2.

Malik Oda 1F

If a question has multiple parts, such as a, b, c, d, e; does it count as one question or 5 questions in regards to the homework?

Malik Oda 1F

Step- up sessions are khan academy. Step-up sessions really helps breakdown everything and khan academy reinforces it.

Malik Oda 1F

How many questions will be on the midterm?

Malik Oda 1F

It provides an online version of the textbook and Dr. Lavelle said he was going to upload extra supplements onto it to help us in class.

Malik Oda 1F

Is the homework due for week 4 still Quantum World problems or are we moving on to bonds?

Malik Oda 1F

Step-up sessions are definitely worth it. They've helped me out a lot.

Malik Oda 1F

I've noticed that everyone's names and discussion sections appear on chemistry community and I don't recall if it was mandatory to set our name that way, but if it is can someone please tell me where I can add my name and discussion section?

Malik Oda 1F

Is there any YouTuber anyone can recommend that would be a good source to use for further supplementation?

Malik Oda 1F

If I made 6 posts week 1, am I allowed to only make 4 more for week 2, or do I have to make a minimum of 5 posts a week no matter what?

Malik Oda 1F

For my other classes our grades are posted under the class CCLE website so I was wondering where to find our grades for Dr. Lavelle's class since the CCLE link opens Dr. Lavelle's website. Thank you

Malik Oda 1F

Do we have to have the units memorized for the test or will we be provided with a formula sheet?

Malik Oda 1F

I was reviewing topics for the chemistry test 1 and I looked over the solution manual and noticed that in problem E.1, the solution converted all the way to km. Would it be okay if I left my final answer as pico-meters rather than convert to meters then kilometers if a similar problem were to show u...

Is week 2 homework due during week 2 discussion or week 3 discussion, since we had one week to due the first home work assignment?

Malik Oda 1F

Are the chemistry community questions definitely due on Sunday October 6th and not by lecture tomorrow? I was told that they are usually due Sunday during a peer learning session but I recommend you try to get them submitted before lecture tomorrow because the TA was unsure if they are still due on...

I called Macmillan directly and the man that provided me with support said it was an issue with everyone at UCLA. He just had me sign under the access code, write the date, and email him the picture of the code, then he enrolled me into the course from his end. I recommend you call them directly at ...

When do we have to have 5 posts on chemistry community by? Because in my peer learning session, the TA told us they are usually due on Sundays at 11:59 PM. Just want to clarify. Thank you.

Malik Oda 1F

You can purchase it for $64 dollars from the sapling learning website. If you make an account and select Dr. Lavelle's course, you get the choice to purchase the online module. Hope this helps!

On the syllabus it states to turn in the homework to our TAs during discussion sections but I thought it was due this Friday during lecture. Where do I turn it in?
