I want to know how many marks in the three papers of Chem Bio Physics will get you a star

 

[L-Girl]

so guys what are the RIGHT answers

 

[Abu mota]

I did that one the same as you..I was mentionibg other-trusted points of views...
That polymers question is wat i am talking about...
A polymer cant belong to the homologus series of alkenes

it is actually called enol and i pasted a link here, it said it is an alkene group and an alcohol group

 

[Skynox]

It is a PVA enol is same as alkanols.will llok into that..

 

[Beedo]

Don't you think that it was a really hard paper 1?!

 

[reya]

and wht bou the uses of fraction n teeth plating ?

B(Negative and graphite)

 

[ShoaibMallick]

what was the answer for the question which had sodium chloride and be seperated from when dissoved in water and also the planet question which gasses were present in more percentage nitrogen and oxygen or oxygen and Co2

da planet one ws CO2 & oxygen....da sodium chloride one i dont rmbr...

 

[ѕ.ɢ сяуѕтᴀʟѕ]

yes its P2Q

it was a repeated question the answer was pq2.

Yah but see they asked us about the concentration of acid and they said the student wanted to change it so every time we obviously have to measure the amount...it was also in one of the past papers no? Anyways it's okay I was also confused about this one and even if we get it wrong it's just one mark.

could u plz give me a link to the past paper with that question
And yes yr right its only 1 marks.....

 

[EpicLol]

Graphite and negative...
Again,the question remains how can a compound belong to two homologus series !!!
That's quite not possible

\
just like how amino acids contain 2 functional groups.....

 

[EpicLol]

da planet one ws CO2 & oxygen....da sodium chloride one i dont rmbr...

no there was 24% oxygen whereas on earth its only 20%....so its oxygen and Co2 yr right..... I put only CO2 that was such a silly mistake D:

You said it functional group but NOT HOMOLOGUS SERIES...

 

[EpicLol]

You said it functional group but NOT HOMOLOGUS SERIES...

yea but if it has 2 functional groups then the same reason why it has both the charecteristics of the homologuous series.....so to be precise the answer should be a different homologuous or no homologuous but since there was no option of no homologuous its both

They should also have same general formula..There was an option of none..According to your sayings,ethanol belongs to alkanes and alcohols ???Absolutely no..

there was an option of none?!?!?!? then I think I got that one wrong :*(

 

[Skynox]

There was and i dunno if what i said is right or no,but i guess,hopefully..It surely cant be alkene since polymers are saturated..

do u remember any other questions? I think I lost about 3 marks....hope I still get an A*

I'll add them to this post in few minutes...
