OMG CHEMISTRY UNIT 1 PAPER!!!!!!!!!!!!

[Wearewhoweare]

okay so since that one is figured what else was there ? I actually liked the MCQ oh was phophorus a giant atomic structure or a small molecular ?

I put small molecular

 

[OrlandoBloom<3]

Oh I put giant atomic ! wait lets google the answer

 

[OrlandoBloom<3]

Btw are you guys giving unit 2 for chem and bio ?

 

[sunnyclone]

You had to write that
less energy is released since electron affinity is an exothermic process

wait it is less negative so it increases right?

 

[sunnyclone]

Hahaha yeah I wrote that too that smaller fractions are more useful than heavier ones . I read in the text book right now that alkenes are obtained from the cracking of alkanes so that could have been one of the answers but I didnt write in the exam The second point I wrote was to obtain hydrogen

i wrote that too..... it forms hydrocarbons with smaller chain lengths to be formed as fuel and to produce hydrogen

Jus chem 2..not a bio student.

 

[OrlandoBloom<3]

Okay I just googled and its a giant covalent structure , it says that although phophorus has a small molecular structure white phosphorus is an exception to that rule and has a giant covalent structure

Oh okay not physics either?

unit 2 in june thankfully
but tomorrow is physics x.x

 

[sunnyclone]

i put it as small molecules as it is not in the same group as silicon and carbon with giant structures but is in the group of N2 which has a small structure

 

[OrlandoBloom<3]

wait it is less negative so it increases right?

I didnt write about the less negative thing whatever it always confuses me , all I know is electron affinity decreases down the group because the size of the atom increases and the no. of shielding electrons increase so the incoming electron is less attracted and thus less energy is released

ahh damn were they talking about white phosphorus in particular?

i wrote the perfect explanation but the wrong statement >.>

^this

 

[Mewan95]

Im doin physics..lol.

 

[OrlandoBloom<3]

Btw yes what was the answer for the theoretical question , I got confused in that

 

[OrlandoBloom<3]

^this

Yepppppppppp it said white phosphorus in the question

 

[OrlandoBloom<3]

Im doin physics..lol.

Omg I did CIE physics last year and it was a horrible experience for me

 

[instaexam]

check the link I thnk u r ryt..I wrote 1/5

that link is about gases and not solutions so it isn't relevant

shit
