If you search up "week 10," you can find a few review worksheets posted by TAs!

Celena Kim 2I

YEs, the more positive E potential would be the cathode while the more negative E potential would be the anode.

Celena Kim 2I

Does anyone know when the answers will be posted?

Diana Chavez-Carrillo 2L wrote:Are we turning in our homework for week 10 to you through email?

Yes we are.

Celena Kim 2I

My TA also said that Lavelle made the midterm this quarter, so it might be likely that he is the one making the final this quarter as well.

Celena Kim 2I

States would remain the same.

Celena Kim 2I

In acidic solutions, you add H2O first to balance the O molecules and then H+ to balance the H molecules.

Celena Kim 2I

The reducing agents typically tend to be the substance with the more negative E potential. The couple with the more positive reduction potential will be where reduction occurs and therefore, contain an oxidizing agent.

Celena Kim 2I

It will cover the rest of thermodynamics (second page of outline 4) and all of electrochemistry (outline 5)

Celena Kim 2I

We will get them back during Week 10 Discussion

Celena Kim 2I

I believe it will be fine to do any homework problems from the sections that will be covered in Test 2, since the TAs know we will need to be getting more practice in.

Celena Kim 2I

Test 2 is not cumulative. It will cover the 2nd page of Outline 4: Thermodynamics and Outline 5: Electrochemistry.

Celena Kim 2I

I'm sure it can be anything from the outlines that will be covered on Test 2, especially electrochemistry.

Celena Kim 2I

If you go to your TA's office hours, they can go over the solutions in depth!

Celena Kim 2I

Sadly, there are no extra credit opportunities :(

Celena Kim 2I

Any material Lavelle teaches after he finishes the electrochemistry outline will not be tested on.

Celena Kim 2I

Some people choose to take 14BL with 14C, but I am personally planning to take them separate since I don't think I can handle both at the same time. I was planning to take 14C spring quarter and then 14BL during the summer session.

Celena Kim 2I

Reviewing and practicing through all the homework problems several times would definitely help, as well as going to workshops and step-up sessions. It also definitely helps to look through outside sources such as Youtube videos from the Organic Chemistry Tutor

Celena Kim 2I

It could be homework questions from thermodynamics and/or electrochemistry!

Celena Kim 2I

Test 2 will be covering the 2nd page of Outline 4 as well as Outline 5.

Celena Kim 2I

Entropy values will be given to us; we won't need to memorize them.

Celena Kim 2I

Thank you for creating this summary!

Celena Kim 2I

Why does it matter if something is a state function or not? How does it affect the problem/question? I'm very confused. It matters because if you know it is a state function, you know that only the initial and final state matters. Since the path doesn't matter, you can subtract, add, multiply, and ...

Celena Kim 2I

Unfortunately, there are no curves on exams :(

Celena Kim 2I

Thank you! Referring back to this during final week as well :)

Celena Kim 2I

The midterm will be cumulative of everything we learned up until Gibb's Free Energy!

Celena Kim 2I

If you search up "worksheet," you can find a few! I believe Hannah just posted one recently from her session.

Celena Kim 2I

Based on his midterm and final in Chem 14A, it will most likely all be free response.

Celena Kim 2I

Kate Swertfager wrote:How similar will this practice test be to the actual midterm?

I believe it will be pretty close since they are going to be past midterm exam questions.

Celena Kim 2I

Is it just me or is the link to the review problems not working?

Celena Kim 2I

I believe it will be covering past exam questions that were on previous midterms.

Celena Kim 2I

The homework should be Thermochemistry problems from Outline 3.

Celena Kim 2I

When a reaction is exothermic, increasing temperature would cause the reaction to shift towards the reactants while decreasing temperature would cause the reaction to shift towards the products.

Celena Kim 2I

The TA doesn't take attendance, but having to turn in your homework during discussion basically requires you to be there.

Celena Kim 2I

Typically partial credit is given, but it really does depend on who is grading your exam.

Celena Kim 2I

There's never been any extra credit opportunities sadly :(

Celena Kim 2I

When will the midterm be?

Celena Kim 2I

No, Kb and Ka values will usually be given somehow; you just need to know how to solve for that value if you happen to be given pKa or pKb instead.

Celena Kim 2I

Yes, the problem will typically give you delta H when asked if the reaction is exothermic or endothermic.

Celena Kim 2I

If temperature is increasing and delta h is positive, reaction will shift towards products. This is also true if temperature is decreasing and delta h is negative. If temperature is increasing and delta h is negative, reaction will shift towards reactants. This is also true if temperature is decreas...

Celena Kim 2I

We won't need to know about it on Test 1.

Celena Kim 2I

When you reduce a reactant, the concentration of the reactant will go down, therefore the equilibrium will shift towards the left to make up the number of the reactants lost so that the concentration will go back to equilibrium.

Celena Kim 2I

I enjoy lectures where there are plenty of examples and a step-by-step walkthrough.

Celena Kim 2I

Yes, both the midterm and final are cumulative.

Celena Kim 2I

It will be during your discussion Week 3 and it will cover Chemical Equilibrium and Acid and Base Equilibria.

Celena Kim 2I

It's also a good idea to practice Acid and Base Equilibria problems and turn that in since that's what Lavelle is covering this week.

Celena Kim 2I

I heard from my TA that there is an automatic system that checks to see if you posted 5 minimum questions by the end of the week.

Celena Kim 2I

There are probably not, but it is best to practice the homework questions since one might pop up on the actual test and for extra practice, outside problems that you can find online.

Celena Kim 2I

Week 3 during your discussion! Your TA will announce it during ur discussion class this week and Lavelle will probably announce it tomorrow during lecture too.

Celena Kim 2I

I think you just need to have 50 posts by the end of the quarter, but it's better to be safe than sorry and post 5 minimum every week.

Celena Kim 2I

If I have a question about a homework problem from Acid and Base Equilibria, which subforum should I post my question under?

Celena Kim 2I

Yes, since that is what Lavelle will be covering still during this week.

Celena Kim 2I

My TA told me they will be graded on completeness, but check with your TA to be a hundred percent sure.

Celena Kim 2I

Does anyone know if a free pdf version of the Solutions Manual is available anywhere?

Celena Kim 2I

Organic Chemistry Tutor! His videos on Youtube are super helpful and detailed, and he goes through many examples.

Celena Kim 2I

5 posts minimum on Chem Community are due every Sunday night at 11:59 pm!

Celena Kim 2I

Iron heme complex is important.

Celena Kim 2I

When will the answers for the final review packet be posted?

Celena Kim 2I

How would you determine which is the stronger base?

6C.17 Which is the stronger base, the hypobromite ion, BrO2, or
morphine, C17H19O3N? Justify your answer.

Celena Kim 2I

Madeline Phan 4H wrote:How much of the acid-base section is going to be on the final? I'm not sure what to focus on.

Acids and bases is probably be one of the topics I would focus on more since we haven't been tested on that yet.

Celena Kim 2I

The test is cumulative from all topics we learned at the beginning of the quarter, but will mostly have an emphasis on the second half.

Celena Kim 2I

I never took AP Chem during high school and I took honors chem during my freshman year of high school so chem 14a has definitely been super difficult for me. Alot of these concepts are completely new to me and I don't even recall learning them during my freshman year.

Celena Kim 2I

Final will be cumulative and covering all topics from Week 1. Definitely scary but I'm hoping the review sessions will go in depth on what will be on the final :o

Celena Kim 2I

I have pretty high hopes that Lyndon will be making a practice review for the final :D

Celena Kim 2I

I understand how you feel! The best thing to do is just practice a bunch of homework questions and practice questions online. Once I start getting everything right, it definitely boosts my confidence so much once I take the test, knowing I have the concepts down. The nervousness will disappear once ...

Celena Kim 2I

We should getting an email about it soon and also a link to the review sessions on his website.

Celena Kim 2I

Some TAs don't really care about sig figs but they do say that it is best to practice having the right sig figs now since you'll eventually need to in the future.

Celena Kim 2I

Talk to your TA during their office hours!

Celena Kim 2I

Going to step-up sessions are definitely helpful! In addition to practicing worksheet problems from those sessions and hw problems, watching Khan Academy or Organic Chemistry Tutor videos are also super helpful if you need to learn from scratch.

Celena Kim 2I

^^ It is cumulative but I also believe majority of test will be covering topics we learned after the midterm.

Celena Kim 2I

Just know the basic intermolecular forces and their relationship with melting/boiling points.

Celena Kim 2I

Step-up sessions tend to be the most helpful!

Celena Kim 2I

Let the TA know and walk over the exam with them during their office hours!

Celena Kim 2I

My TA said it will be covering outline 4, just the topics we started learning after our midterm.

Celena Kim 2I

My TA said that Test 2 will be covering Outline 4

Celena Kim 2I

I've been reviewing questions and correcting the questions I did wrong on the midterm and Test 1 as well as reviewing homework questions from the textbook.

Celena Kim 2I

Does anyone know what the next test will be covering?

Celena Kim 2I

I believe you can sign up for tutoring through AAP.

Celena Kim 2I

I'd like to be in one too!

Celena Kim 2I

Don't think there is any, but I really wish there was some extra credit opportunities to help me jump back from that midterm grade lmao

Celena Kim 2I

Looking over past exams you can find from the test bank at SAC would also be a good idea too.

Celena Kim 2I

Going over practice questions posted on Chem community from workshops and review sessions are also super helpful

Celena Kim 2I

Chemical Bonds section!

Celena Kim 2I

This section on Khan Academy would be super useful to you!

Celena Kim 2I

I know that one of the questions from the homework will be a test question, but can someone point me to a section of questions that have test-like qualifications? I want get some more practice, so like a recommendation to a challenging problem in the book would be appreciated. The questions covered...

Celena Kim 2I

Definitely look over and practice the questions from Lyndon's review session last Friday that he also posted on Chem Community. The packet was super helpful!

I was super confused before when I focused on only doing a few problems from each section, but after running through all the probl...

Celena Kim 2I

Work on chemical bonds homework!! That is what will most likely be covered during discussion so it's best to work on them ahead of time so you'll have questions ready for your TA to help you work on.

Celena Kim 2I

The midterm will cover everything we've learned so far (fundamentals and quantum world).

Celena Kim 2I

Drake Choi_1I wrote:Does anyone know if there will be mutiple choice? Or will it solely be problems?

I think it's pretty likely that there won't be any multiple choice questions.

Celena Kim 2I

Since Test 1 was already only allowed to be written in pen, it's likely the midterm and final will also need to be in pen.

Celena Kim 2I

Do we have to recognize charges of certain elements?

Celena Kim 2I

Most of the math that will be done is algebraic--isolating variables and rearranging equations. As long as you can do that, you won't have to worry about the math being too difficult!

Celena Kim 2I

Do you know if in future tests, we will also be provided with a formula sheet?

Celena Kim 2I

Is the midterm only going to have questions based on Quantum World and Fundamentals?

Celena Kim 2I

Considering that a few SI conversions (like nano) were given on the first exam, I'm not sure if they will also be provided on the midterms, but it's better safe than sorry to try and remember as much as you can!

Celena Kim 2I

I've heard from plenty of students already that the Step-Up and Workshops held by Dr. Lavelle's UAs are extremely helpful, and they're free! So make sure to try and take full advantage of that first; I definitely am!

Celena Kim 2I

As long as the calculator is not a graphing calculator, any scientific calculator will be fine.

Celena Kim 2I

Showing work is best because the TA can follow along every step and give you max points for each step.
