AS Chemistry P2 Prep.

[RGBM211]

Lol so many answers lemme answer my question in short the one which has polar bonds shows the most deviation and is easily liquified and thanks evryone

 

[MysteRyGiRl]

ohh GOD but wasnt da answer CO2???????

 

[RGBM211]

N2 because it has the biggest temporary induced dipoles out of all of them, due to having the most electrons. All the molecules there do not have an overall permanent dipole

its CO2

Please stop confusing just imagine what if this question appears in exam i will b like superconfused

 

[TheMan123]

its CO2

Please stop confusing just imagine what if this question appears in exam i will b like superconfused

oops my bad! didnt look at all the gasses

 

[MysteRyGiRl]

its CO2

Please stop confusing just imagine what if this question appears in exam i will b like superconfused

lol if it dos come in da exam u will be luckiest prsn alive

 

[MysteRyGiRl]

btw i just made a mistake in dis so just wanted 2 post here incase any1 makes da same mistake
in da PV=nRT equation dont 4get 2 cnvrt cm3 by multiplying it wd (10^-6)...i 4got da cube part
anywayz BEST F LUCK evry1...plz do pray 4 an aswum ppr IA

mmm do we always multiply cm^3 with 10^-6....lil confused here isn 1dm^3=1000cm^3 :O

this may be a stupid question but can someone help me with this....Burning 1.00 g of octane produces 48.4 kJ of energy. Calculate the heat energy
produced by burning 1.00 g of methane ??

for these questions u have 2 convert cm3 to m3 as m3 is da standard form.so cm to m is 10^-2 but its cm3 so to change it to m3 its (10^-6) ie into 3

use mcQ

wooow thanks but i ws thinkin isn the volume taken as dm^3 as well ok fine its m^3

 

[MysteRyGiRl]

yes ur ryt.volume is alwayz in dm3 but this is a GAS equation.here its m3, presure is in Pa and R is 8.314 and temperature is converted in k.if its in degree celcius just add 273 to change it 2 kelvin

no problem

hw was the paper guyzzzzz??//
mine was good ....there were just 4 qs.....wowww

 

[Saad (سعد)]

Don't give out information about the paper; like how many questions there were or other things more important than that, before 24 hrs. o_o;

But anyways, I screwed up in the first question; gonna probably lose 3-6 marks there, but Al-Hamdulillah the next ones went well; I expect full or only one or two mistakes in them.

Overall, I think I'll get an A insha'Allah easily, but if I get 90% (at least 54), then Al-Hamdulillahi Rabbil-'Alameen!

 

[Almostdoctor]

How was it guys?

 

[fathimaash]

da paper was mashallah fine.. hope we get As for it

 

[Ammirul Shafiq]

alhamdulillah..a few silly mistakes.but i leave it to HIM to 'mark' it.tawakal
