Chemistry P1 and P2 today

[Kinza Zimri]

kinza ur ans is wrong

no chance of it getting correct at all?

 

[ritx]

higher in reactivity so displaces X

what was your answer to th number of moles of CO2? something like 0.004 moles? and the mass of calcium carbonate 0.4 g?

 

[Shadow]

I chose the option: decrease the pressure. what did u choose?

They asked the effect of increasing pressure on position of equilibrium ... Position shifts to left as less gaseous moles were present on left side (if i remember the ques all well)

and the mass of calcium carbonate was 0.4 g RIGHT?

I chose the option: decrease the pressure. what did u choose?

100/158 x o.500 makes 0.31.

Idk for sure, I dont remember clearly :'/

 

[danial 234]

r u sure?? i also wrote H+ and NO3-

this is wrong. the compound was ammonium metavanadate. you can check on the net

 

[Haris Sal11]

r u sure?? i also wrote H+ and NO3-

No :/ Wrong.

 

[Kinza Zimri]

Im out of here for some time. This thread just makes me feel miserable. I ruined the paper.

No, i want to know wat was decomposed to produce V2O5, water n gas Z?

Ksi ko yaad hai to plz tel me, m getting curious

precise chances are there i believe

 

[Amnaa]

I wrote NH4+ and H+

H4NO3V

 

[Haris Sal11]

I got the mass of CaCO3 0.31 grams. 100/158 x 0.500.

 

[qasim9]

NO! It's correct.

Is it ?
Cuz i wrote'the'same thing !

 

[ritx]

nope

They asked the effect of increasing pressure on position of equilibrium ... Position shifts to left as less gaseous moles were present on left side (if i remember the ques all well)

we were discussing an MCQ up there.

 

[Kamihus]

C3H7COOH is right ans

nope its not, it was A

 

[Shadow]

H4NO3V

then ammonia is correct i wrote NO2 coz the eq of decomposition of nitrates sprang to my mind at that time it always produces NO2

 

[danial 234]

I got the mass of CaCO3 0.31 grams. 100/158 x 0.500.

vol of CO2 could be taken frm graph . convert it into moles . use the equation to find mass of CaCO3

 

[Shadow]

nope

we were discussing an MCQ up there.

hahaha n i was lyk wat r they all saying?

 

[danial 234]

nope its not, it was A

what was A
