bhai dafa kr ab.I think i already said that if final twmp. is 90 how is it not possible, 90*C does not exceed boiling point of water , read the whole question not just the marking scheme GENIUS
can you recall more details about question?What was the ans of that Test tube one's MCQ?
it had numbers in options... 1 2 3 4 ???

It was 3 , 1st 3rd 4th test tubeIt was 2 , the second and the third testube
which ester diagram we have to make structure onlyAWESOME , 99% correct , but i think i lost 1 mark in the ester diagram
It was 3 , 1st 3rd 4th test tube
which ester diagram we have to make structure only
I wrote 1st titration vol 25.3 as it was 25.2 which slightly changed my answer of average further my answers to part a b c were change
for example
.000506 mol but i wrote .000507
how much max i will be penalised plzzzz help
yes, of course there was a reaction in 4th. As far as I can remember, there was magnesium rod dipped in Cu2+ solution. I triple checked. 3 was the right answer.There was no reaction in the 1st and 4th test tube, as there was a copper rod in a solution of mg ions in 1st test tube, dont remember the fourth but pretty sure there was no reaction
*diagram my bad
I am saved, by this i only lost appx. 2 marks in whole paperin the mark schemes they require prescise anwers , as for the titration vol i think if you mess up one volume they consider it all wrong .
You are right i also did this, only 2nd reaction was not feasibleyes, of course there was a reaction in 4th. As far as I can remember, there was magnesium rod dipped in Cu2+ solution. I triple checked. 3 was the right answer.
and for the very same reason, I wrote 0.0005 only,I am saved, by this i only lost appx. 2 marks in whole paper

What was the answer of colour change in titration question
mass of CaCO3 used was 1.8 g, percentage of iron was 8.7% in mixture, titration average volume was 25.3. Magnesium Ribbon was silvery white. Emprical formula was C3H8O. Molecular formula was C3H7OH. And ester was propyl prponate. anything more?
which paper ? 32 ??AWESOME , 99% correct , but i think i lost 1 mark in the ester diagram
