How was 9701_w15_qp_22 ?

Does any one remember the mass of mgso4? and laso what was the answer to the third part of enthalpy change ?

 

[The Sarcastic Retard]

one mark for this statement and one mark for writing "according to markovnikov's rule.....(your answer here) ""

I lost 1 mark here then..

mass was 3.01 I guess.
Answer to that is -94KJ/mol

but accordi

one mark for this statement and one mark for writing "according to markovnikov's rule.....(your answer here) ""

ng to the markovnikoves rule any element is added to the carbon which already has maximum numbers of hydrogen. so I think it had something to with the negativity of bromine ?

m

Answer to that is -94KJ/mol

mine were 88kj-mol

 

[Alishba fateh]

so

m

mine were 88kj-mol

so the heat transferred had nothing to with the mass of mgso4 only water were taken

according to markovnikov's rule the bromine atom will attach to the carbon (one with the double bond) with less hydrogen and hydrogen from HBr to carbon with more hydrogen atoms.

 

[The Sarcastic Retard]

so

so the heat transferred had nothing to with the mass of mgso4 only water were taken

mass of mgso4 was used to calculate moles .

 

[Alishba fateh]

mass of mgso4 was used to calculate moles .

according to markovnikov's rule the bromine atom will attach to the carbon (one with the double bond) with less hydrogen and hydrogen from HBr to carbon with more hydrogen atoms.

So this is it, I think many would loose marks on small stuff.

 

[The Sarcastic Retard]

True. Silly errors.

So this is it, I think many would loose marks on small stuff.

 

[The Sarcastic Retard]

I am setting my max error to be 15 marks, it cannot exceed this limits, and till I know GT is always varying b/w 43 to 48.
Fingers crossed hope GT is low.
Hows ur all prep for paper 3??

 

[Alishba fateh]

mass of water and temperature changes?

 

[The Sarcastic Retard]

mass of water and temperature changes?

It was in question only.. 45g and temp was 11.8 maybe

 

[Alishba fateh]

It was in question only.. 45g and temp was 11.8 maybe

mass of water want 50? or maybe I forgot

 

[The Sarcastic Retard]

mass of water want 50? or maybe I forgot

It was 45 till I remember..

 

[Alishba fateh]

It was 45 till I remember..

and what were the number of moles?

 

[The Sarcastic Retard]

and what were the number of moles?

0.025 what about you??

 

[Alishba fateh]

accor

0.025 what about you??[/QUOT
according to all the figures youve provided the answer should come 88 kj -mol

 

[The Sarcastic Retard]

accor

That's the answer to the above part of the question it was 85

 

[Alishba fateh]

accor

yup the same
