Thanks so much! I hope they put one of those sneaky yield questions on the real paper now:)

5:53 you should also get that mark by saying it heats more gently, trying to accurately heat with a bunsen is incredibly hard and takes much longer

Hi this is incredibly helpful thank you so much.
At 13:04 I was abit confused on where the 122 for the mr came from, was it worked out or did you add the elements ar from the periodic table to get it?

Hii, for the first question a) - would i still get the mark if I said increases the surface area to the gas ratio? Thank you!!!

Why is percentage yield sometimes done in moles but sometimes in mass?

For the last part of the question. Can you use Mr for ethyl benzoate early in the question and find mass using moles times Mr, then find percentage yield using the mass given.

Hi sir, based on the advanced information for AQA, RP10 is listed with the alkenes topic. Do you think they will only ask questions for required practical 10B since that is the preparation of an organic liquid?
