AP Chemistry 2024 Free Response Question #3 - SOLVED!

[@xray8270]

we did NOT cook guys

[@keshkeeper14]

We got cooked, I specifically got cooked so bad I might as well be well done

[@samarth1812]

Talk for yourself dude. I cooked more than Walter white ever did in his life time. Getting a 5 for sure. The multiple choice was so easy as well

[@d00p58]

im actually so cooked i didnt realize it wasnt galvanic. we gettin a 2 on this one

[@daveforfav7650]

Same. I got positive 0.43

[@JoshCoder-Orphanizer]

WE ABSOLUTELY FREAKING COOKED 🗣️🔥‼️

[@The_Horizon]

this is so light compared to form e 😭

[@thecriscokidd290]

Probably xD Keep playing minecraft!

[@petergriffin8086]

form o mcq was david goggins hell week 😭🙏

[@The_Horizon]

@@petergriffin8086 mcq from form e was significantly harder than last years exam too. Praying for the nice, juicy, heavy, sweet curve on that

[@loaid2078]

Yo the horizon took ap chem? I got form E too it was hard.

[@clapz8191]

Form e cooked me 😭

[@ttraumei]

thank you very much Mr KruG!

[@JeremyKrug]

You’re very welcome. Thanks for watching!

[@nevaehwren3192]

I have not took the exam yet i rescheduled, do you think me watching the frq videos like these will help me study?

[@JeremyKrug]

It will help, but remember that the make-up exam will be completely different from the May 6 test.

[@InsanityoftheSanities]

Chat I don’t think I’m getting a3

[@trezzyVal]

If i did the right E cell calculation but only because i read the next question to find out it was flipped but forgot to flip my balanced equation do i lose both points because of consistency

[@millie7768]

OMG I ACTUALLY GOT THIS STUFF RIGHT?!!?!

[@nyemawalker]

Im so mad i was doing so good . Over half on all the questions but on the e cell one i forgot you don’t multiply by 4 when subtracting 💔and ive never made that mistake before . Literally sold the easiest question. Therefore my E cell was positive so i said it was galvanic causing me to loose even more pointsssssss

[@JeremyKrug]

Hopefully you were able to do well on the other questions. There were some tough ones on here!

[@quakewyd.]

for the last part, do you lose points if you have more than 2 sig figs?

[@fossyl1205]

my teacher didnt teach us the substitutional alloy thing 😭😭

[@JeremyKrug]

Ouch. It's actually early in the course, Unit 2, Topic 4.

[@selmabahy9027]

Are these points all or nothing? For example, for 3(a), I said the correct oxidation number for Ag(s) but not the correct one for Ag2S(s). Would I be able to get a half point?

[@amazinf4344]

All or nothing, makes me tear up

[@selmabahy9027]

@@amazinf4344 rip :(

[@JeremyKrug]

I think that part is all or nothing, but CB might give a point for each. We'll have to wait for their official key to find out for sure.

[@148zeus]

this was by far the hardest question

[@man743_plays_da_games9]

For part e, i got like 3977 or something like that with 4 sig figs is that fine?

[@ifrizix7914]

Does anyone know how the mcq are graded?

[@DanteAtanassov]

If you got it right or wrong

[@ifrizix7914]

@@DanteAtanassov😂of course but I heard some people saying it’s out of 50

[@dolphin601]

Wait a minute.... I never got any of these questions

[@ethanlei8317]

thank you mr krug you are the AP chemistry savior this world needed

[@JeremyKrug]

Thanks so much for the kind words. I hope you get the score you want on this exam!

[@AlfredDu]

Mr. Krug is always the goat

[@JeremyKrug]

Thanks!

[@vinuchandra2008]

I stupidly multiplied by 12 moles of electrons instead of 3 😂😂

[@colescott3969]

I got 5/10 q1 9/10 q2 and an 8/10 on q3 💀💀💀💀

[@familyc3845]

For the question that asks why the process needs an external power source. Could the answer that I put be correct that the reaction was generally non spontaneous and ended up having a negative standard E cell? I did not mention that the proceeds was not thermodynamically favorable whatsoever

[@ZivoTBG]

Not being thermodynamically favorable is essentially the same thing as non spontaneous. I think you will still get credit..

[@nolaneng]

Yes, you would’ve still gotten points. Not spontaneous is another way of saying not thermodynamically favored, they mean the same thing!

[@JeremyKrug]

That answer sounds good to me

[@bereketkiros7454]

For 3 b(ii), could mentioning electron-electron repulsion be a valid justification for the difference in atomic radii?

[@mizuari2675]

That’s what I said

[@thatguy720]

I said this as well, but I also wrote about how it had more energy levels than copper does.

[@bereketkiros7454]

@@thatguy720 yea same

[@suryakridhey1475]

All i wrote was that there is 1 mor energy level so there is a bigger radius for that one. Will i get the point?

[@obligatoryidiot]

depends on the grader, but unfortunately probably not

[@daina9188]

nahh I cooked!!!

[@Chen-rz2tg]

i forgot to do sig figs for the last one..

[@nolaneng]

Sig figs aren’t required anymore unless the question specifically asks for it

[@daveforfav7650]

I did terrible on this frq 😭😭😭

[@spacium-3030]

If I wrote 3896 s or something along those lines instead of 3900 seconds would I lose all points on that section of the question due to sig figs, or would I still get credit?

[@man743_plays_da_games9]

Sameeee I need to knowwww

[@spacium-3030]

@@man743_plays_da_games9 Ya, it's esp scary for me, cuz it determines if I got a 4 or a borderline 5 since I did that for a lot of questions... :(((

[@kaisalwawi4515]

Only 1 question on the whole frq deals with sig fig. That means it only matters one time if you used correct sig figs.

[@spacium-3030]

@@kaisalwawi4515 No, across all the FRQs (I could get the right answer but lose up to 5 points on each individual question (1 pt per question) due to this which would just be pretty sad)

[@man743_plays_da_games9]

No literally sameeeee hopefully they are chill??? Idk how they take off pts for sig figs

[@nihaarjampala2718]

I cooked

[@lol_unbeatable]

i'm so cooked

[@sleepysombra]

that makes one of us...

[@cainebit]

for e isnt it 12 moles of electrons???

[@richardmurray9303]

Nah that was after the conversion to make both sides equal

[@courtneyestella2014]

no cus we're talking ab the Rh ion itself and how many e it needs so since Rh ion is Rh 3+, it's 3 mol e

[@hi-pb5zt]

I used 12 too smh

[@kevinzhao4353]

First

[@Mitblade]

In D and E I got cooked hard

[@CM-rw1xu]

Me too

[@Na0811te]

I got cooked on this one but did good on the last one I think

im cooked
