What's that ?
And again homologus series should have both same general formula and same functional group..General formula is CH(2n+1)OH

i was talking about the 3rd question about the apparatus, do we need a measuring cylindar

 

[Rahma Abdelrahman]

What did you write for the question about at which pH is there both acid and salt???
I wrote D...

 

[salvatore]

Ethanol should have 5 hydrogen and esterification is not polymerization..ethanol according to several ms
Cant polymeriZe so alcohol cant

I counted 5 hydrogen there.. or was I blind or something?? According to what I know, a polyester is formed by condensation polymerization! But never mind.. its just one mark!

same

same ...what bou the teeth plating one ??

i was talking about the 3rd question about the apparatus, do we need a measuring cylindar

yeah that one was repeated

 

[19loko97]

yeah that one was repeated

so what was the answer

 

[Rahma Abdelrahman]

same ...what bou the teeth plating one ??

The carbon layer is graphite as it is a good electrical conductor and terminal X was negative

 

[Skynox]

so what was the answer

PQRS

what about the vanadium oxidation question? i wrote the one V2O3-V2O5 and the iron question i think it was iron is easier to extract than copper not harder anyway i wrote the one with transition

Same for oxidation....and no the more reative the metal the more hard it is to extract from its ore..

 

[ahmed soliman]

the question was saying easier not harder!!!!!!!!! anyway if it is wrong i am going to get 39 inshaallah

dude one mark can brin a A* bt rong meanz nth can b done nw

 

[ahmed soliman]

the question was saying easier not harder!!!!!!!!! anyway if it is wrong i am going to get 39 inshaallah

as far as i remember

 

[Skynox]

as far as i remember

No it was harder in the choices...

 

[ahmed soliman]

np just 1 mark the rest are correct inshallah

 

[Skynox]

Organic wat did you get for the homologus one ?

 

[ruler_of_the_world]

Chill guys n forget it cause its gonna make u more worried so jus pray...wats done is done n if u have any remaining exams focus on them n i wish u all the best! XD

 

[ahmed soliman]

remind me with the question plz

Organic wat did you get for the homologus one ?[/quo

 

[Omar Hosny]

Guys the acid and salt question I did it area D ? i want someone sure to tell me is it correct or not ..
Also oxidation was V2O3 -----> V2O5
functional groups I wrote all right
