Shayad 5400

4200 kj 1mol of CO= release 210KJ
Moles of CO in 560g= 560/28= 20
20mols of CO= 20x210= 4200KJ

 

[Nouman1997]

but mine was 4200 kj

Han Han sorry 4200 hi tha yad a gaya

Kisi ne endothermic wala question attempt kia tha

Kisi ne endothermic wala question attempt kia tha

dynamic equilibrum wala

 

[Nouman1997]

Han

The two Ions were:
- Ammonium ion, NH4 +.
- Metavanadate ion, VO3 -.

WTF wasnt it NO3- And NH4+ ions

 

[ijlalm]

what was the ans of KJ question?? was it 4200KJ?
And why does MgCl has a higher melting point than NaCl?..i wrote b/c of stronger electrostatic forces of attraction between oppositely charged ions and a higher energy is required to break them

 

[Saad Mughal]

WTF wasnt it NO3- And NH4+ ions

That's not possible.

yeah i attempted that one

 

[ijlalm]

That's not possible.

Could u recall the question plz.!!

 

[ijlalm]

everything is possible..as far as ive heard

 

[Saad Mughal]

Could u recall the question plz.!!

H4NO3V, which TWO ions are present in compound X.
If NO3 - and NH4 + were present then the ions wouldn't fit the formula of the compound!

It may. But it seems lame.

 

[ijlalm]

Are u taking computer studies..if u are..have u prepared the subject?? Theres no gap.!
Systems flowchart scare the hell crap out of me

 

[Saad Mughal]

Yeah, I am. I didn't open a computer book for 4 months before last week. I studied the whole syllabus from the IGCSE book last week before the English and Chemistry papers.

IAM TOO GOOD TO FAIL.. FOR PETE' S SAKE HELP!! (NOT NOW BAAD MEIN)
