i did unit 2 and 3. I was pissed that i forgot to mention that when heating the gases that tongs need to be used. But hey - u don't need 100% to get an A. I also got worried that on most of the writtren questions i had to write beneath the lines cos i couldn't fit it in. I probably was quite inconcise. I hope that they are kind markers. Im FREEEEEEEEEEEEEE!!!!!!!!!!!

i put just cryolite for part 1 and brine for part 2. I should have put bauxite ore dissolved in molten cryolite as u said. Damnit! I better get an A for both units or i will probably kill myself.

I put (bauxite) Al2O3 for 1st and brine(NaCl) for 2nd. But why it's 3 marks? Maybe need cryolite in 1st one. I didn't notice the mark, I think 1 one for each
