wat u mean with these marks.....?

what I got out of 200 as I calculated....I think these would be an A*....but not so sure.....

 

[Skynox]

In this quesiton the answer is both alkene and alcohols.... (B) so the homologuous series can also be both......View attachment 13041

That's not a polymer !!

 

[EpicLol]

That's not a polymer !!

nonononono Im not talking about the polymer question but the question where it said what are the homolouguous or functional groups present in this compound and it was similar to this..... (Not sure which on it was.....)

can u calculate for me my marks in the thread I posted...plzzzz

Yes it was carboxylic acid and alkene.
Which functional group does this contain ^^

Please repost your marks in all the 3 papers here....
Thx

yea 31 overall in chem
36 overall in physics
25 overall in bio (maybe less)
about 7 in maths
english 40 marks(impossible)!!

Why is the answer to the salt and acid question D?? It can be C as well right as at C there is some salt formed and there is still acid left that is neutralising the thing more.....and then so on...

Im really sorry I can calculate for math phys bio but english its different and I did not take english and what about chem and could u tell what u got in like paper1 and paper3 and paper 6 of each subject coz they have different weightnings.....

I did the same

 

[Beedo]

What is the final answer till now about the functional group question and the polymer question?

 

[Skynox]

What is the final answer till now about the functional group question and the polymer question?

No one knows..
And about the acid C was before pH 7 so there was still some alkali to neutralize..

Oh..I just thought about it now and it should be D
because there is salt formed + the excess acid
Should I suicide
Lost 4 marks till now

ok
1)Bio....p1=39-40
p6=55
p3=about 65
2)maths....p4=only 4 mistakes
p2=about 1-2 mistakes
3)phy.....p1=38-39
p6=about 55
p3=about 58
4)chemistry
p1=36-37
p3=about 70
p6=about 51


plz grade me now!

Believe me those are A* if you are pretty sure those are the only marks you lost

And about the acid C was before pH 7 so there was still some alkali to neutralize..

but the question asked when there is acid and salt present not excess acid, therefore, C has the salt and it also has some acid as the neutralisation is still going on....and the acid that is there is reacting with the alkali that is present as well.....

but the question asked when there is acid and salt present not excess acid, therefore, C has the salt and it also has some acid as the neutralisation is still going on....and the acid that is there is reacting with the alkali that is present as well.....

The acid was added to tha alkali not the opposite...
So,at C the ph was above 7 the solution was slightly alkaline...

listen are u 100% sure that the letter c was above 7 or below? If C was below then thats teh answer. but when u think abt it, D was on the straight line, meaning the reaction didnt start yet. So no salt wud have been present in D

chem = 175/200
Phys is 168/200 but paper 6 was not out of 60 marks, but only 40....
Maths = 190/200 (Not entirely sure about this one )
Bio = 187/200

C was clearly above ph 7 by 0.5 cm or so..
To get the correct answer you should know which reagent was added..
The acide was added to the alkali
So the pH decrease from 12 till it becomes acidic..
