Did anyone use pKa = pH for that pH curve one? What did u get?

 

[OJL2018]

Like the same level? I got X for the chalk brand what did other ppl get

I calculated 83.5% so i did Y

 

[tywebb]

paper attached but it is out of order at the moment. maybe better version coming later

EDIT: see post #311 for better version

bro where were we taught this with hsc resources and syllabus?

I got x…

got X too

 

[tsswhzl]

got X too

Did y’all get 2methylbut2ene or 2methylbutene for the last question

In 24 multiple choice they use that

 

[tsswhzl]

And wtf was the salt question in 1L of water. All I could think of was the Ksp values but they weren’t there

 

[lawfirm]

got X too

ChatGPT says X

 

[iane]

anyone got answers for Mcq

Did y’all get 2methylbut2ene or 2methylbutene for the last question

think 1st one

 

[tsswhzl]

think 1st one

ChatGPT told me I was wrong I swear the double bond was ok C2 though

yeah cuz didnt it have to form a tertiary alc

2methylbut2ene cuz if it is 2 methyl Irene then it will produce a primary alcohol however compound c is a secondary alcohol

I said 3-methylbut-2-ene which is technically the same, reckon I’ll get marks?

yeah i got that
hopefully its right

I think if its just the final compound name you we would all get 3/4 if the reasoning is relevant

 

[iane]

I just drew the structure I didn’t include a name

 

[almost_done]

if we just drew it is that ok?

 

[C_master]

For q19 I got C
And 20 I got b

Are those right?
