please explain <3

@synthesisFR @carrotsss

 

[synthesisFR]

more solvent x = decrease concentration of I2 in x --> eqm shifts right --> decreases concentration of I2 in y?

 

[synthesisFR]

how many chem and 4u math papers have u done now btw
i need some nice 4u math paper recommendations. as long as they dont have like the pulley questions ill do them

 

[SadCeliac]

oh that's actually smart lol

i thought

add x means increase conc x --> shift left --> decrease Keq

you seem correct

@carrotsss opinions?

 

[synthesisFR]

add x means increase conc x --> shift left --> decrease Keq

no bc x is the solvent only

THERE IS NO DAMN WAY YOUVE DONE 30 CHEM PAPERS WTAF HOLY SHIT THATS INSANE

Every paper has a explain how soap works wuestion I wanted to die

 

[synthesisFR]

I’ll do nsb 2022 today for 4u ig

 

[SadCeliac]

Every paper has a explain how soap works wuestion I wanted to die

but that's literally free marks wtf


soap has polar head / non polar tail
hydrophobic tail dissolves in non polar grease
friction from rubbing action lifts up grease molecule from surface and allows for more tails to dissolve
once tails have fully surrounded --> micelle
emulsion of soap water and grease micelles is rinsed away with water

bam clean

I can't really post all the spectra here but basically how do we determine if something is ethyl ethanoate vs methyl methanoate based on H NMR and mass spec - the answers say that I was meant to justify based on that, but their HNMR and mass spec are (in my theory) identical???



jokes ill post the specs (screenshots are from the criteria so those are the marker's annotations)




yeah okay

 

[SadCeliac]

got 85 in this paper btw just finished marking <3
