Best SEA Admit brother ever!

michellebui_3L

Search up "churro" if you want practice problems for concepts from the midterm and beyond, and "garlic bread" for practice problems before the midterm.

michellebui_3L

It's the regular 7 problems, not like the 14 from last week.

michellebui_3L

You could ask friends who have already taken the class and see if they have old tests or course reader.

michellebui_3L

The final will be cumulative with no topics in particular weighing more than any other.

Saima Salam 3J wrote:I also had a question about the final. Does anyone know how many questions would be on the final? Would it be similar to the midterm (8 questions)?

There will be 8 questions with subset questions, covering everything that we have gone over in lecture the past 10 weeks.

michellebui_3L

We have to memorize it. The only formulas/information that we don't need to memorize are the ones that have been provided to us so far on the exams (tests and midterm).

michellebui_3L

I'm pretty sure there isn't a curve for this class and that it's based on a point system. However, if you do get 50% (250/500 points), then this is the exception to earning a C-. He mentioned this in lecture once.

michellebui_3L

I would recommend focusing on homework for chapter 4 since that is what will be focused on for Test #3.

michellebui_3L

There is no curve. The class is a straight scale, however if you get at least a 50% in the class then it will be a C-

michellebui_3L

The last day of class is Friday of week 10 and our final is on Sunday. There won't be any classes scheduled during finals week except for any finals or review sessions.

michellebui_3L

The final will be cumulative, focusing on the latter half of the material we covered after the midterm and it will also include pre-midterm concepts, but not focused heavy on those topics.

michellebui_3L

Test 3 covers: End of Bonding from 3.12 (6 Ed.) and from 2D (7 Ed.); and all of Molecular Shape and Structure (see Syllabus and Outlines for details). This is was Dr. Lavelle posted on his website.

michellebui_3L

I would think that they would be on his own class website Does anyone remember what the website was that Dr. Lavelle mentioned in class that has learning modules similar to the ones we had for the first units? I could be wrong but I remember him making a comment about more learning modules. I think...

michellebui_3L

Some people who don't have a strong foundation in chem like to take Chem BL after taking Chem 14B, but if you have a solid foundation in chem, then some people like to take it together because when they're studying for BL, they're also studying for B.

michellebui_3L

While discussions are still taking place the rest of this week, we don't need to hand in our homework for this week until week 9. Therefore, during week 9 we are handing in 14 homework problems.

michellebui_3L

Unless Lavelle/UAs made an announcement, I think the workshops will still be held the rest of this week.

michellebui_3L

During winter quarter, you might get dropped from the class if the pre-requisites or co-requisites aren't met.

michellebui_3L

I thought that everyone was turning in their homework during discussion during week 9?

michellebui_3L

Does anyone have the link to Sapling?

michellebui_3L

so if like we get a 65% what grade would that be since a 50% is a C for the final grade? You should just keep track of your points since the class is based off of a points system. If you didn't do so well on the midterm, you could make up the rest of the points based off of your final, Test #3, etc.

michellebui_3L

For those with Thursday and Friday discussions, will we be handing in our homework to our TAs during Wednesday lecture (given that we do have lecture)?

michellebui_3L

Does anybody know how we will turn in homework for Week 8 if we have discussion on Thurs/Fri?

michellebui_3L

I'm pretty sure you'll be able to submit homework from Outline 3 since we are barely covering VSEPR Models in class, so any of the chemical bonds stuff should be fine.

michellebui_3L

Our last test will be held during Week 9!

michellebui_3L

Thanks Ronald! And thank you for the extra help during your drop-in hours!! -No problem, Michelle! :)

michellebui_3L

I think anything but a graphic calculator should be fine.

michellebui_3L

I believe so, since the Thurs/Fri discussions during Week 0 make up for the Thanksgiving Thurs/Fri discussions.

michellebui_3L

Can anyone help explain the process for 11a Thank You! You can use the equations (-hR)/n^2. Use two of these equations and plug in 1 for n and 3 for the other n. You could also manipulate the equations and subtract the diff so: ((-hR)/(n^2))-((-hR)/n^2)). After, you find the answer, divide it by h ...

Atomic radius decreases from left to right, therefore Aluminum would have the bigger radius since it has less protons.

Does anyone know how to do question 13 a and b? I though I could do 13a but thirteen b said that what she did (which is what I did) was wrong. She can't divide the speed of light by the wavelength for each potassium ion because you can't use the equation for the speed of light since potassium is an...

michellebui_3L

Due to the Thanksgiving holiday, Test #3 has been moved to Week 9.

michellebui_3L

Attend review sessions and going to office hours; doing the homework problems and modules.

michellebui_3L

Attend the review sessions, office hours, step-ups, and workshops. Also, do all the modules and homework problems.

michellebui_3L

Can someone post the notes from that review session?

michellebui_3L

8 questions with subparts. The midterm format will be similar to our past exams.

michellebui_3L

Sunday @ 11:59 p.m.

michellebui_3L

Going to office hours to see if you really really know the material and be able to teach it to someone else. Doing all of the modules and homework problems, especially since one homework problem will be pulled and incorporated into the test.

michellebui_3L

I believe it's a review of high school chem, quantum, and chemical bonds, so Outlines 1-3.

michellebui_3L

I think Lavelle would tell us on Monday in lecture about the Midterm. I'm pretty sure it would cover Outline 1-3.

michellebui_3L

The last test should be during Week 9.

michellebui_3L

Where can you check the test average?

michellebui_3L

Sunday @ 11:59 p.m.

michellebui_3L

Test 2 will cover everything up until the material on Friday of Week 3's lecture .

michellebui_3L

Each test/midterm/final does not receive a letter grade because your final grade is not accumulated until the end of the quarter. This class is based off a number of points and those points are calculated at the end once you receive all of your test scores from Week 1- Finals Week.

michellebui_3L

For Test #2, would the test focus on the topics covered on the outline in week 2? (Ex: Photoelectric Effect, Atomic Spectra and the Bohr Frequency Condition, Wave Properties of Electrons and the De Broglie Equation, and Heisenberg Uncertainty Equation)

michellebui_3L

If you forget one week, but make up the net week and do 6 would that still count?

michellebui_3L

Also going to jump on this thread: m.bui3931@gmail.com Thank you!

michellebui_3L

The number of points accumulated will be totaled at the end. So, while you may have done well on this first test, there are still 2 more tests, a midterm, and a final, as well as discussion and homework still to be factored.

michellebui_3L

You should get your tests back during you discussion section during week 3.

michellebui_3L

I think it will be given at a later date closer to the midterm. Usually, chem midterms are from 6-7:50pm.

michellebui_3L

Q: What do you call an acid with an attitude?

A: A mean-oh-acid.

Week 4: Test #2
Week 6: Midterm
Week 9: Test #3

Q: Why can't we trust atoms?

A: Because they make up everything.

Q: What did the scientist say when he discovered 2 Helium atoms?

A: He He

The questions asks to find the length of the fiber when we are given a radius of 144 pm and 1.00 mol of Ag. How would we solve this problem to find the length of the fiber?

michellebui_3L

Hi Ashley,

Although I'm not pre-med/pre-dental, etc. your words of advice are still very helpful! Thanks for continuing to give back to the UCLA community and the students here as you were once in our shoes. Best of luck in med school

michellebui_3L

The homework that he posted is only for the 6th and 7th edition, so I don't think the 5th edition would be helpful since the homework problems don't cover the 5th edition.

michellebui_3L

Do we get partial credit on our homework problems if some of the work shown is correct?

michellebui_3L

You only get credit for doing 7 problems, but doing all of the problems will help you to prepare for tests.

michellebui_3L

All of these chemistry jokes are sodium funny. I slapped my neon all of them.

michellebui_3L

What did one ion say to the other ion? I've got my ion you.

michellebui_3L

I can't think of any more chemistry jokes. Because all the good ones Argon.

michellebui_3L

The homework is to turn in 7 problems. But, what about the modules that we need to do? Is that just for practice for us?

michellebui_3L

It's kind of something you just have to learn and get used to. It gets harder when it's a covalent bond, but I figured ionic bonds are easier to name.

michellebui_3L

Either is fine, but pen is required for exams.
