The last question was tricky, I was able to do the first 2 parts, I got 4 and 1

for the % by mass question I got around 60% but idk if it's right...

those two questions were the only really tricky ones I found though... damn maths

not looking forward to CH4 and CH5, especially CH5 since there's so much damn colours to remember for the redox reactions and the p and d block reactions... plus it's the same week as PH4 and M1... end me

You guys are talking about the new spec right?

For the percentage yield question, did anyone else get like 80%? I remember sitting there thinking it couldn't be right but I had to move on because I didn't have much time.
Also, for the last question, I got a molecule with the formula C5H6O2, ended up drawing a pentagon with a few double bonds. I got 5 different bonds like the IR spectrum thing said so I think I was on the right track.
