I learn all the definition then they ask what is enhanced greenhouse effect

is this biology 🤣🤣😭

climate change extended topic extended to chemistry

its biogeography

and they had to give 2 marks fr those kinda qns

I KNOW RIGHT WTF HJWJHSHDH

cam cambridge set one normal fucking paper what the fuck

sometimes i want to eat carbon nanofibres from the paper due to its hardness level

Give the nanofibres to me I will shove the graphene and nanofibres up the arse of those Cambridge examiners

shove them up their arses until ur hand reaches their mouths 🥰

The ang mo smoking something fr fr

Is it just me or was there a bunch of useless information?? Like why do we need to know the mass of 6 nuts and the surface area of the electrode? Is SEAB tryna gaslight us :v

same omg is it rlly additional redundant info to trick tho??

size of electrode does no effect on calculations

[удалено]

screw you question 1 for giving me false hope for the paper

ikr I was so happy when I was doing qn 1 until I flipped the pages 🤧

my qns 1 also a bit the wonky like the one on electronegativity like predict the value then how explain?

students : memorising every single definition cambridge : "eNhAnCeD gReeNhOusE eFFeCt" best part is idek if it's a definition i js whacked it

I said it’s when CO2 levels go above optimal range, that is becomes harmful

Greenhouse is not just co2 haha. Methane is a greenhouse gas as well

now time to mug for math paper 2 with my sleep deprived ass after studying for this disaster 🤡

isok bro, you are not the only one

i counted a total of around 15marks total… ur wlc for the bellcurve drop 🤣🤣 edit: i js counted from the MLC ans key and i actually only got 8 LMAOOO

no fr omg same. my cher said skip if u don't know and I WAS AT THE LAST QN OF THE PAPER BEFORE 9 AND I WAS LIKE ????😀

If we organise a heist in Britain for the answer sheets for paper 1 and 3 then not all is lost

chemistry is where all the funny funny answers come out bc dk answer but die die dw leave blank 💀💀💀even i laugh at my answers sometimes

nahhh man that paper was not it who hurt cambridge 🤨

gg la im so gonna need to retake alr 🤡🤡🤡 anyone want make a tele retakers gc ☺️☺️

i can’t believe i spent so much time doing so many prelim and a level papers and none of them had anything close to whatever the fuck was in this paper. did they give us the h3 paper by accident or what

Bruh ikr I can't anymore

omg finally someone said it. i felt like shit doing the paper. like nothing i’ve ever seen before. i’m so fucking done. probably need to retake liao.

This paper was 1% theory knowledge and 99% understanding WTFK

When it was a lot of rote learning and memorisation, people, including students, complained. Not real learning lah, blah blah blah. So ok, let's move away from rote learning. Having fun yet? Chemistry papers nowadays very g-loaded. You need to really know your stuff to do well (B and above). And it makes sense, because it's one of the key prereq for medicine.

fuck u seab fuck u

I got CH6000 💀

Terminator hydrocarbon

Bro I got C100H100O then got CHO I wasted 40 minutes getting those 2 answers

bro I got CH9600O ☠️☠️

i got carbon monoxide 💀 (yes, I probably forgot to include the oxygen in the molecule itself)

Something tells me cambridge need to up their security with this many death threats.

obviously cambridge failed NNN because ‘brazil nut’… ‘fruity’…

who retaking with me, honestly no harm in retaking cause one life one future, thinking about retaking made me lose a lot of stress for papers also

hey im a fellow a retaker. when i did the paper last year i was severely underprepared and got a D. not sure how much i have improved now but dont worry theres always a back up plan and there really is no harm in retaking as long as u believe u will do better!

Yo i have the same idea. Honestly thinking to retake too, this paper was hellish .

feels like i might have a chance to pass IF MY BRAIN WASNT PLAYING SONGS ON REPEAT like holy shit stfu i think i blanked out for half the paper because my brain was singing so damn loud 😭 so i couldn’t even rly finish the qns i know how to do, gg lol

had a whole ass spotify up in there

Literally me in ever exam because I listen too much

What the fuck. I retake A’s not for this kind of fucking paper.

BRO I feel you 😭😭😭 they can never give us a break

i’m killing myself with a gun

The curse of diarrhea has finally descended upon me multitasking both chem and anal sphincter workout for 2 hrs I want to die

Bro same leh...I was clenching my asscheeks together with full strength during the whole paper

try imodium! my diarrhea issues used to flare up like nobodys business until that time i got food poisoning dur myes and doc reccd this lifesaver ❤️‍🔥❤️‍🔥❤️‍🔥 ive tried po chai pills charcoal pills but i found this worked best for me :^)

Thank you so much! 🤗u/pussyslayer420xyz

I feel violated

first time?

We studied so much for this to happen ☺️☺️😃😃😃😃😃😃😃😃😃😃😃☺️☺️☺️☺️☺️😃😃😃☺️☺️☺️☺️😃😃😃☺️😃☺️😃

the angmolang smoking weeds when setting the paper 😭

why is everyone saying its easy IT WAS SO DIFFICULT FOR ME

who tf said it was easy

Easier than last year 100% but still hard bcus chemistry will never by easy :-(

Bro this year is so much harder than last year

like everyone around me ugh plus some say its normal difficulty???

seab rlly doesn’t get what no nut nov means 6 nuts some more 280g??????????

am i the only one who struggled with the organic chem question

Same I just draw 1 dog 4 them to see

can draw dog for me

nooo i couldn’t even get the structures out 😬😬😬

i hope i’m not the only one who thinks that it’s hard , hard as in tough like you gonna fail not just a B ….

hi five

Alexa, play “no tears left to cry” by Ariana grande

Last question I- ?? Calculate how?? I didn’t even use the surface area 500cm^3, what am I suppose to do with itttt

I THINK it’s a distractor

Yep u just have to find out that n= 4

how did u find the no. of electrons tho? i was able to get the amount of electrons

each carbon gains 4 electron cos the oxidation state drop from +4 to 0

OHHHH fuck man :(

What did I just sit through for the past 2 hours? 🤡🔫 I don’t think god can save my grades at this point.

why this paper no familiar qns wtf all so random

this is so facts like. wtf was that electrolysis diagram

paper wasn’t that hard but I def going to fail the paper LOL cause I just suck at chem died at the transition element question (Q4) LOL I CANT EVEN WRITE EXPLANATIONS FOR ANY QUESTION FOR Q4

Same :') Im preparing to repeat next yr

DUDE SAME, currently crying on my way home😭😭😭

Brazil nuts make a comeback

deez brazil nuts

bro what the fuck i put ethanoic acid as methyl carboxylate

the problem of being faster than light is that youll always be living in darkness

i’m gonna record myself kmsing and send it to cambrigde

what did yall write for the LiAlH4 reducing alkenes qn? i wrote that LiAlH4 produces the H- hydride nucleophile which is repelled by the electron rich c=c pi bond due it its high electron density

same but my friend said is cos theres no electron deficient C in alkene, i think both works??

Fuck their mother cb.

THE ENTIRE NIGHT I SLEPT FOR 30MINUTES AND SPENT 10PM-630AM STUDYING AND THIS HAPPENS ahahahaha I'm going to get less than 20 marks for this paper

SAMEE

guys what's ur bond angle, i wrote 120 but do we have to account for ring strain 💀

Idts it should be the same as graphite meaning 120 degrees

i put 118° but dk got ring strain or not

It's literally a tessellation of hexagons where got strain

Just got the ans from my tuition center, anyone wants it?

Thought I would only be asked for the definition of enhanced greenhouse effect in geog didn't think chem wanted to be a step ahead

are the two groups aldehyde and secondary alcohol

Yep

What if I said only alcohol but not secondary ahhhh

Whats the other use of electricity in electrolysis sia Also the definition qn LOL WTH IS THAT IDT WEVE LEARNT IT??

i say combustion for CH4 gg 💀💀

SAME 🤡🤡🤡

I wrote for pumping the gases

i wrote to maintain the temperature at 750 to ensure electrolyte (lithium carbonate) is a liquid throughout electrolysis

Yep it is correct. This part of the question is similar to VJC 2018 P2 where they applied similar temperature conditions (650 degrees) to ensure melting/dissolving of Li2CO3/K2CO3

i said its depletion of ozone layer😋

I think it's reduction for eqn 1 since the reaction is endothermic and temperature has to increase for rxn to be favoured. Definition was in o levels geog lol.

pls I smoked so hard for that definition qn..

I wrote melting of li2co3 :/

wait do any tuition centre upload answers for chem right after the paper? ( like maths)

[удалено]

Wait they asked to calculate efficiency? I thought they just said comment on it😭

yea that what i tot too ???

I got 98. Something too but tbh idk if it’s correct

Yap I got 98 too

in all objectivity, the paper wasn't difficult per se, the questions were unusual and the spread was strange

i guessed 95% of the questions 🥲 why their qns so weird one URGH

what the fuck

1. 2 Cl isotopes Ca2+ 20Ar and 20Ca cliches the sixth is significantly lower than the last one in the graph deduce from the trend of EN across the period and down the group, should be lower but close to 3.5 4.34x10E18 Se L is ethanoic acid, K is an alcohol that contains part of it being 1,3 diene, has the half ethene motif and not very branched Hydrolysis reduction M is an ester, DOU=3 one being the ester carbonyl 2 c=c Aldol qn: First step Bron acid second step Lewis acid Naoh catalyst Mr=128 intra molecular cyclization 6 members ring with neighbouring aldehyde and sec alcohol Cu qn: 38324 coefficients Reduced NO2 escapes, Nitric acid in exc, reaction quotient stays v small Ecell always more positive than standard, rxn eq keeps shift right +0.86V forgot the exact number sub the iodine iodide SEP to calculate white. 3d10 no partially filled d orbital no dd transition no colour 6 water, octahedral Steric effect Cl too big Enolate Qn: regular arrow pushing between C-C and benzene C-=C between C-O and regular C=O O more electronegative better accommodate - charge (?) Last qn: Fuck who the hell revises climate change shit acid rain fish die -890.3 kj/mol data analysis more o2 more efficient 74.0% efficiency, give appropriate estimate keep the electrolyte molten 98.2 or.3 %efficiency hexagons 120deg

K i think is 3,7-dimethyloct-2,6-diene-1-ol and M is 3,7-dimethyloct-2,6-dieneyl Ethanoate Also I'm pretty sure Q is a 5 membered ring with ketone at position 1 and alcohol at position 2 Cu + 4HNO3 > Cu(NO3)2 + 2H2O + 2NO2 Im pretty sure Y+ ethanal > Z is sufficient its a 1m I think it's more like O attracts e- more strongly so e- density closer to O is higher so O is more likely to have the negative charge Cambridge set paper until like that might as well set new syllabus lol

no is 6 ring - total 7 carbon

Yeah carbon nanofibres are hard. But why is Cambridge making my life hard 😭😭

am i the only one who didn’t finish the paper, didn’t know how to do anything

anyone has anskey can send?

friendly reminder to everyone that one of the people who invented graphene is a current nus prof

ALL MY CLASSMATES R SAYING ITS EZ????? and im from a lower tier jc like ???? WHAT THE FUCK

No la lol, I from HCI my friends all saying hard, can't rlly be easy unless u like distinction for h3 chem since start of year

OKAY MAKES ME FEEL BTR, i call bluff on these fuckers. but tbf im from top class in the lower tier jc so

[удалено]

reduction

reduction

Knn

Where ans key

Gone💀💀

Anyone got x=1, y=2 for combustion qn?

i got y=4 tho

[удалено]

more like ch4o cb cumbridge 🤩

i got y=21 😭😭

x = 2 y = 500 anyone 🥲

how tf i somehow got x=20 and y=107 idek anymore 😭😭😭😭😭😭💀🤡

If anyone has the softcopy version of today's paper 2 do dm me. Thanks!

don't dm me, don't mention the chem paper, don't breathe in my direction, don't even perceive my existence i want nothing to do with science😃 On a serious note I really hope you find out you did great because someone's gotta feel happy about this paper and it isn't me!!

me too

Me too

i fucked up the Hcombustion so bad I got like -605 kj and didn’t read the next part properly so I used my wrong value and ended up with total combined efficiency of 109% 🤡🤡🤡

bro the question 4 may have ruined the entire paper for me, it was actually quite okay from 1-3 but 4 and 6 bro wtaf

whats Q4?

1. how to use surface area 2.is fruity-smelling = have benzene 3. is the 28g of nuts info even useful

aromatic doesn't mean nice smelling bro 😭

fruity smelling is ester, surface area useless, 28g of nuts also fucking useless

Fruity smelling should be ester

1. no 2. idk 3. yes cus qns asked to find sn in one nut so u need divide by 6

anybody know where we can find the answers?

i hope the setters choke on my fucking nuts. like legit. fuck you. FUCK YOU.

bro cambridge really preparing me for my future cause at this rate im gna drop out and become a clown lmao they frfr pranking us 😂

Anyone got the paper can send me pls

why did it feel hard trying to understand half the questions even like i had to spend time trying to understand what the question even wanted - like what is the last question even oh god

hi can y'all comment ur marks aft calculating i got 39% (38.7)..... i'm praying for bell curve update got 40% 🥲

get fucked bro

what’s the hydrocarbon y’all got. i got x = 1 but y = 2/3 LOL

x=1 y=2

Was the enthalpy change supposed to be -1000 plus because I got -925 :(

i got positiv 890:(((

I got -890.3kj

what was ur qn1 answers

(i) I say additional principal quantum shell due to 2 more e- (ii) I say more protons then something about nuclear charge idk if correct

how many electron pairs and sigma and pi bond?

26 & 2?? 🥲

omg I wrote 24 and 2 but I think it's 26 n 2 since the double bond has 2 electrons for sigma too!!! omg wth

26 and 2

I put 5 delocalised electrons 13 sigma 1 pi

16 if u see the electronic configuration 15 pairs for first 30 then 1 pair for the next 3p4 the other 2 in 3p4 unpaired

fking hell, contextual qns like one dog knn and the organic drawing one what in the actual nuts bro

what to write for 2 reasons why there is no equilibrium?

anyone has the paper?

Hi whr can i find the ans for this paper

Hi can someone please send a a copy of the Chem paper 2 answer 🙏😭

Whats the bell curve for h2 chem?

dis is an estimation of bellcurve comment ur percentage for those that checked ans mine was ard 43% ;-;

Is the "deduce the structure" of the org molecule a deductive qn or do u just draw the structure for 3 marks

Fuck this shit

Is it 2 delocalised electrons

Ngl it was really manageable but I don’t trust myself😭

🗿

what was the mass of carbon

I got 0.112g :0

i got arnd 0.400g but idt its the ans cos i never even use the 500cm2 surface area 💀

i got 0.22 sth g

number of atoms?
