GUYS,, I DIDN'T DO WELL IN CHEMISTRY PAPER 6...

[hard_worker]

i drew a beaker with rods inside, and a test tube up. dont knw if it right though!

i drew a delivery tube!!

 

[nadalrafa19999]

Delievery tube is correct. In Q1 you had to draw the trough diagram with test tube upside down and the tube from the trough going to the carbon rods. In the other diagram you could have drawn a gas sringe

what about the cracking thing y was the tube discarded

 

[nadalrafa19999]

I wrote that it may conatain iumpurities

guys i did variant 1 , it was realllly hard .. especially question 4 anyone ?

Don't know. I wrote that first break the large lump into small pieces and add HNO3. This will result in the formation of PbNO3 which is aqueous. Then add a piece of iron metal into the compound and a displacement reaction will take place and lead will start to form on the base of the beaker. then it can be filtered off and dried

I wrote the same thing but with the displacement reaction i wrote to heat it .hope that this answer is right!

first page what apparatus shud we draw ??
and the cracking Qn why was the first tube discarded ??

first tube of gas was discarded beacause a small alkane will also form even hydrogen gas is accepted

 

[jashanva]

and guys for variant 2 i used the wrong acid but my mehthod was 100% correct how many marks will i loose all or maximum 2 marks

can we say ethene obtained is not pure

 

[Xylferion]

I don't know but since it's catalytic cracking, I figured that since both the alkene and alkane are formed, that maybe the first tube could have been the alkane rather than the alkene.

Well I did that paper too. Really liked the very last question

i drew a diaphragm cell...similar to the electrolysis of brine in industry...hope that is correct...

I did variant 1 wasnt that had tbh , what was the most tricky question you faced ?

the questios of titration and i stumbled in labelling the arrows of the liebig condenser .. btw did u do biology ? i found that also difficult

Did you find paper 32 of bio hard? What do you think the threshold for A* will be?
