what was the answer to the atom economy question

what was the answer to the atom economy question

how many marks do you think you have got

molecular mass of desired product/molecular mass of all products x 100

for that question ?

What did you do on the question for international awareness of incineration of plastics?

for the last question I've drawn out the structure of the alcohol, carboxylic acid and the ester but I didn't put down their names... Do people think I would have lost a mark for not naming them?

If they said name them then yes probably

I was in hurry when i was doing the last question so I didn't read the question properly... I thought I've done quite well until I saw other people discussion and I think I've already lost 10 marks ... all silly mistakes !

Well only 10 marks wouldn't be terrible. Still a bloody good A

I might have lost more marks... anyway the grade boundary will be quite high as everyone is saying

high i think they will be lower

I think this paper is the hardest paper out of all papers I've done... So I hope the boundary will be low low low !!!
