Thank you guys, this topic makes a lot more sense to me now:)

LillianHarvey2C

There were about three or four questions about pH on the test, hopefully you felt confident enough answering them:)

Color coded flashcards, and also writing the formula in a red (or any vivid colored) pen tends to help me a lot:)

Music helps sooo much

LillianHarvey2C

These replies were extremely helpful. I also like to leave my dorm and take walks around campus to clear my mind, sometimes it even helps me to think of ideas when I'm struggling with my assignments. Whatever we stress about won't be a permanent feeling, it'll get better eventually:)

LillianHarvey2C

Thank all of you guys for the advice, it was really helpful and I really needed to hear some of these things. Hope you all have a great winter break and get a grade you're happy with:)

LillianHarvey2C

I'm glad the final is over because it was the one I was most worried about. I'm still a little stressed about my potential score but I'm still glad I got it over with. I'm looking forward to later this week when my friends and I hang out before we leave for winter break. I hope everyone has a great ...

Oh I've watched the Great British Baking Show before too:). My mom, sister, and I like watching cooking shows, especially [censored]'s Kitchen, together.

LillianHarvey2C

Some of my favorite cartoon-like shows will always be Spongebob and Total Drama Island too:) A lot of you guys in the chat have good tastes.

LillianHarvey2C

Thank you for the encouragement. I know the test is over but I'm still stressing about it in the back of my mind lol. Hope everyone receives a score that they're happy with:)

LillianHarvey2C

Now that the final is over, unfortunately I still feel stressed because now the worry just shifts to how I think I did. Hopefully everyone is feeling a little better though. Good Luck guys:)

LillianHarvey2C

My Thanksgiving break was pretty good, it went by quick. I was happy to see my family again and my cat:)

LillianHarvey2C

Ohh, yea I figured it would be included in the score likewise to the other two midterms we've taken. Does anyone know if there's going to be a curve for the final?

LillianHarvey2C

Wow thank you so much. I always love the music Dr.Lavelle plays in class but when I ask Siri what song it is, it never works probably because of the echo in the lecture hall. Glad I don't have to look for them:)

LillianHarvey2C

Two chemists walk into a bar. One tells the bartender, "I'll have an H2O." The other says, "I'll have an H2O too!" The second chemist dies. Hahahaha, morbid but still really funny. Also sidenote, but why would the bartender actually still give him the chemical to drink? That's t...

Haha it's the pause of suspension that actually makes it funny lol

LillianHarvey2C

Lol, these jokes actually gave me a smile I needed:)

LillianHarvey2C

A good way I remember that Bronsted refers to protons and Lewis refers to electrons is to remember that Lewis structures show the electron arrangement. :)

LillianHarvey2C

Yes weekly, my TA informed us that the responses we do each week before midnight are recorded.

LillianHarvey2C

This resource was honestly a life saver, I was trying to look them all up on google to refresh my memory lol. Thank youu:)

LillianHarvey2C

Yes, you use the noble gas that's closest to the total amount of electrons for the element without going over the amount, then the remaining electrons are still represented by the same configuration.:)

LillianHarvey2C

I also find watching additional youtube videos on the topic to be very helpful, plus making sure to ask your TA to review your midterms to go over the questions you miss:)

LillianHarvey2C

I also was having issues with this problem on the last homework assignment. When it says my structures are wrong but I'm confident the structure is correct, I always then check my formal charges:) sometimes simple math is the easiest area for mistakes since we don't think much about it.

LillianHarvey2C

Hi, can someone further explain the "50% needed to pass" part?

LillianHarvey2C

At first I was also confused especially when seeing so many signs at first glance, I interpreted it as a greater than sign as well, since that's what I was used to when working with the symbol:)

LillianHarvey2C

Yes this is true, my TA told me to email him or come to office hours so that I could review my midterms. It's very helpful to do so I recommend:)

LillianHarvey2C

The final is still in person even though it takes place on a Sunday, correct? or?

LillianHarvey2C

35% ? wow that's really heavy. good luck on finals everyone:)

LillianHarvey2C

These are all really good pieces of advice! I would also recommend going over the last two midterms and looking over the question you missed, which I believe you can do with your TA by asking to review your midterms. Good luck on finals everyone:)

LillianHarvey2C

Thank you for this explanation, it was really helpful since I assumed species referred to the type of element.:)

LillianHarvey2C

I mostly use the textbook to go over topics that I need more explanation for to complete the homework, since I noticed the lectures don't cover every single term that the homework focuses on. Plus it can also be good for practice problems.

LillianHarvey2C

This is all great advice, I would also recommend going over both of the midterms and looking at the questions you missed, which I believe you can do by asking your TA if you can review your midterms.

LillianHarvey2C

Yes, I was also under the impression that the final will be cumulative and include all the material we have learned so far.

LillianHarvey2C

The grades are out but I'm a little nervous to check mine. I'm grateful for the support system I have of friends and family:)

LillianHarvey2C

Wow I'm so proud of all of us. This time around for the midterm I practiced a lot more book problems and used the homework examples more, and I honesly do feel more confident for this one than the last. Good luck guys:)

LillianHarvey2C

What did the thermometer say to the graduated cylinder?
At least I have a degree!

LillianHarvey2C

Yea unfortunately I don't think there are any extra credit assignments, as told by a former student of the class that I know.:(

LillianHarvey2C

Oh thays good, this was really helpful. However i was also wondering if anyone knows if we'll be given the values that are constants? Or will we have to memorize those with the equations too for the midterm?

LillianHarvey2C

I find the best ways that work for me are working through textbook problems and watching yt videos on the topics since hearing someone else explain it in different ways can help me understand things I maybe hadn't before. You could ask about things youre confused about to the chemistry majors you or...

LillianHarvey2C

I've actually asked my TA in discussion section what he best reccomends for rounding, and he told me to try to only round at the end of the problem since the more often you round in a problem, the further away the answer gets from being most accurate.

LillianHarvey2C

This was really helpful I was also confused on this, but another question I have is does this mean there's no class on Friday? Or if we attend class will we just have to take the midterm there or?

Though very cheesy, these jokes genuinely made me laugh while I'm studying for a quiz. Thank you guys lol Also a very bad cliche joke: My friend and I were making cookies. I told him to get the baking soda, and he then proceeded to open the stove and say "there's no soda baking in here" lol.

LillianHarvey2C

I am also super rusty in chemistry! The last I took chem was my sophomore year of high school and even then it wasn’t my best subject. However I’ve been feeling better about chemistry because Prof Lavelle has given us so many resources! There’s his modules which are practice problems and videos of ...

LillianHarvey2C

I actually did not know this either, but now it makes sense. When referring to viscosity the terms sound close to their meanings. (Low) viscosity means it's more of a (liquid) and (high) viscosity means it's (harder) to pour. L,L and H,H. Idk but thats what helps me remember it lol.

LillianHarvey2C

This thread is so cool, I like to bake and that's also how I realized the amount of similar skills needed in both the chemistry and culinary professions. That's how I learned that solids and liquids when cooking have to be measured using two different sets of measuring cups because the quantities ch...

LillianHarvey2C

Yes, this is very possible. One example is formaldehyde which has the molecular formula CH2O, and glucose which has the molecular formula C6H12O6 and therefore the same empirical formula as the formaldehyde.

LillianHarvey2C

Hello, the actual yield of a chemical reaction will always be less than the theoretical yield because of impurities, substances sticking to the wall of the containers, etc. The theoretical yield is the maximum amount that can be used so it's a b8gger amount. If your actual yield is bigger than your ...

LillianHarvey2C

This is a really cool (and funny) way to remember the conversaions, thank you! However im a little confused on how the example at the end was given, and was hoping someone could explain it a little more. Thanks!

LillianHarvey2C

Thank you for explaining this problem, it was so helpful and I found the simple mistake I made. I accidentally divided the 510 gr by .0545 instead of multiplying the two amounts.

LillianHarvey2C

To the above post: yes thank you for reminding me. I also often have to remember that liquids and solids can still have different amounts when talking about the same units of measurement.

LillianHarvey2C

I had wondered the same thing and so I actually asked my TA this question. He recommended that you don't round any solutions until the very end, since the more often you round your answers during the problem, the further away your answer will be from the actual amount.
