As stated above the oxidizing agent is what is reduced so whatever has highest reduction potential will be the best oxidizing agent and the one with lowest reduction potential would be considered the poorest oxidizing agent.

A coulomb is the measure of electrical charge in 6.24x10^18 electrons.

Hi my school didn't offer AP Bio and I was still able to get an A in the class. The workload is very doable and Maloy gives you multiple opportunities for extra credit. The class itself will require studying like all classes but I wouldn't rely too much on the launchpad. Attend all the midterm revie...

I don't think we have to memorize oxidation numbers just that oxygen is -2 and hydrogen is +1 and deduce the rest from those givens.

Hi this has probably been asked before but just a quick question on chem community points. Is the max number 50, or do we get a point for every time we post answers and questions?

Nicole Critzer 2L

The gas constant you use depends on the units of the given information. So far it seems that most of the problems we've been given do use the 8.314 J/ (K*mol) so I wouldn't stress about it too much. However just make sure to know which constant to use should you be given something in units that diff...

I think getting a C- does let you take 14C because its passing right?

Nicole Critzer 2L

I would recommend khan academy or look up Chem 14C on YouTube, most of the time students have already compiled videos on playlists while taking the courses so you have a general idea of what is going to be covered, in the order it will be covered, and this could serve almost like a study guide while...

I would say instead of reading the textbook attend the UA workshops and step-up sessions. If not those then the organic chemistry tutor on YouTube is also really helpful.

Nicole Critzer 2L

So far I'm enrolled in LS7C and LS40 but I'm not sure if I'll be able to take 14C cause the class is already full. I do have credit for chem 20A and 20L but I'm not sure if I could do Chem 30A as an alternative or if I'm even prepared for that class.

It's not just remember how to derive it.

H2O is water and H2O2 is hydrogen peroxide
What is H2O4?

I'll try to keep this in mind as I study for the upcoming midterm. Thanks for posting:)

You can go to your TAs office hours if you want to review them.

Like others said above Lavelle basically states what outlines to look at in the most recent email.

I binged Queens Gambit and Bridgerton. They were pretty good, I think queens gambit a little more than Bridgerton. However Bridgerton is just like Gossip Girl but in a different time period.

You would have to look at the bond strengths, but simply put it is because the total energy needed to break(add energy) the bonds of the single reactants is greater than the energy needed to form the compound. So because more energy is added than released the overall reaction would be endothermic.

Nicole Critzer 2L

Like others said above you can use either one. However it would probably be a little more work because you would need to ensure you use the correct R and make work negative.

Nicole Critzer 2L

In phase changes I like to think of the phase diagram and in what direction you are going to. If you are moving right along the heating curve you adding heat which is endothermic. So for example going from solid to liquid would be an endothermic reaction because you are adding energy. If you are mov...

I appreciate the tips! But how do you guys check your answers to make sure you're doing them right ?

Nicole Critzer 2L

Hi guys I also work part time and I usually average about 22 hrs a week. Personally I don't think not having a job would make this class any easier for me. I can say I don't have time but the reality is even when I do its hard to stick to my scheduled plan. I am my worst enemy and this recent midter...

Nicole Critzer 2L

I don't remember if this is right but I thought some of the questions had partial credit, but I'm not sure how that works with multiple choice. Is it like one of the answers could have been correct or was like the step before the final answer?

Nicole Critzer 2L

Thanks for sharing, I think I need to change the way I study because I didn't feel as confident on this midterm as I have on others. I'll definitely try to do more of the homework problems.

Le Chatelier's principle is basically how equilibrium will shift to oppose the change caused by the disturbance.

I want to write some jokes about the periodic table… But I don't think I'll be in my element

Nicole Critzer 2L

The test for me was kind of mixed some of the questions seemed pretty doable but others had me really confused.

Nicole Critzer 2L

Well after doing some of the math on some scratch paper I think two things may have gone wrong, when using the quadratic formula to solve for x using your given values I got something different than .016. Second when finding percent ionization I don't think you divide by the Ka but by the molarity o...

It is not mandatory to do the audio visual resources but is highly recommended.

Nicole Critzer 2L

I'm a little stressed. The midterm scares me a little. I just hope I'll be prepared by Friday.

Nicole Critzer 2L

It sounds like we can use any calculator for the exam as long as it's not too advanced.

Nicole Critzer 2L

Thank you so much! This is so nice of you to share:)

Are the textbook problems similar to the homework problems on sapling?

Nicole Critzer 2L

I thought in one of the emails he announced there would be no class on Monday.

Nicole Critzer 2L

As someone who didn't take 14A with Lavelle how is the midterm formatted?

Nicole Critzer 2L

My go to movies are anything from the Harry Potter series or star wars.

Nicole Critzer 2L

I'm confused about this too. I think I have the same problem. I finished today and on sapling it shows I have a 100% but on ccle it shows I have a 97%. Does it take a while to load or update frequently?

Nicole Critzer 2L

In order to get points for each post does it matter how long or short it is? Or is a question or like two sentences sufficient?

Nicole Critzer 2L

Everything on Sapling is automatically graded right? We don't have to turn anything in for this portion of the course?

Nicole Critzer 2L

Hi :)
Is each step up session different? Like do they go over different problems in each session?

Nicole Critzer 2L

Hi guys this is my first time using chem community as well. So far I know how to post replies but how do I post a new question? When I went to the FAQ it said there would be a new post button somewhere below but for some reason I don't see it. Is there another way to post questions?

Nicole Critzer 2L

The midterms overall are probably worth less points than the midterms in 14A
