NS FL5 Physical Sciences Q33

For this question, I was able to get the question right and identified that A/D were the right answer, and also noticed the correct answer also correlating with the carbonic acid buffer. That said, I wasn't entirely able to understand why the answer had to be a base and couldn't be acidic if all we ...

Work of a System: On vs. By

Hello! No matter how much I try to read the difference between work on a system vs. work by a system, I'm still finding myself not understanding how they vary or when to tell the work work would be positive or negative! I'm looking for some clarification or ways to practice this so I wont' get so tr...

Methyl Propyl Ketone

Hi guys, I had trouble drawing the structure for methyl propyl ketone (it's an answer choice for question 1864 in our 2000Q book) and thought it was simply four carbons, but when I googled the compound to double check, it's actually 2-pentanone so it has five carbons!! When I was drawing I thought i...

Re: STRESSEEDD

Just wanted to say you're not alone! I had to postpone my test because I was around that range and wanted to improve towards a similar goal as you! At some point though I do think nerves will begin to make us psych out on what we really know or not! In my FL reviews I find I tend to second guess mys...

2000Q Book: Organic Chemistry #1849

Hello! I'm having a bit of trouble conceptualizing the mechanism for this reaction. I had initially thought that this would be an SN1 reaction because I thought the methoxy group was considered bulky. Which possibly leads to the separate of question of what is a general rule of thumb for what can be...

Organic Chemistry Extractions Question

Hi! I'm watching the Orgo Lab Techniques video and I'm having some trouble understanding what to do when you want to separate two acids, but one is only slightly stronger than the other. Why would you use a weak base to get rid of the stronger acid, and a strong base to get rid of the weaker acid? I...

2000Q Book: Physics #1517

Hi! I was wondering for this question, how do we know to use the whole volume for the buoyant force equation? I wasn't able to understand how we assume the whole volume is submerged, especially since we have half of the block contain a density less than that of the fluid it's submerged in (the dogwo...
