Chemistry P1 and P2 today

[Saad Mughal]

reason?

Heat spreads evenly through a body (courtesy equal movements of electrons). I could be wrong, I could be right.

I'm not an examiner you know.

andaaza -_-

 

[Saad Mughal]

andaaza -_-

Tha kitny marks ka?

 

[asma tareen]

Tha kitny marks ka?

i guess 3 ka

 

[Saad Mughal]

i guess 3 ka

Then 1 or 2, if there was another part then you will be awarded for e.c.f.

I'm sorry but I can't find any reason why you're method is wrong; are you sure that you're applying it correctly? Are you sure that the mass of the tablet was 0.5 g?

Yes 500% bro. It was given at the very start of the question.

 

[Saad Mughal]

Yes 500% bro. It was given at the very start of the question.

Well, it had to be 0.632 for your method to get 0.4 g. Sorry, can't help you with this now.

 

[Haris Sal11]

Well, hoping for A*'s in these CIE's. INSHA ALLAH. Thanks for the complement.
Yeah, two things;
- No aluminium was mentioned.
- They asked the TWO ions that were present in the compound.
Gave off the answer to be Ammonium ion and Metavanadate ion.

Need to know. Did it state that 'ONLY' two ions are present?

 

[Saad Mughal]

do u know the exact wordings of the electrons question i forgot the wording

I didn't even read the whole question!

 

[Mustafa Malik]

oh i understand the situation...no problem

but seriously there is a skool who has actually plans so that it students can prosper. I hope u understand what i mean

Well, I didn't study the solubility of gases, but I knew which ones were insoluble. Although, I didn't even take in account the solubility of the gases in the MCQ!

Same here dude...

It stated THE two ions present. 'The' emphasizes on only.

 

[Haris Sal11]

It stated THE two ions present. 'The' emphasizes on only.

I think it said that the solution was acidified and NaOH was added and Ammonia was given off. Write down two ions present in the solution?

How come H+ was present if the solution was acidified? If the question specified that only 2 ions were present, I think I'm wrong then.

 

[Saad Mughal]

th
then boths answers r correct

Lol, I wish.

It specified that state THE two ions present, also, I cross-checked the compound on google, it was ammonium metavanadate which contains ammonium and metavanadate ions.

There was an mcq in paper that to reduce magnesium oxide, u'd heat it with carbon, sodium, copper, or hydrogen? What u wrote as the answer?

 

[Mustafa Malik]

Same here dude...

Both of u and EVERYONE ELSE can u tell me one thing
I heard that in paper 1 full mark is not deducted even if we get the mcq wrong?????? There r mostly 2 ans ( right 1 is from them) which r better than others. If we chose any from them partial credit is given. Also check the first page of paper 1 where instructions r given.

That's non-sense. You might get credits for wrong or partially correct answers in Theory but NEVER in MCQ's.

impossible! nobody would get a U then !
