Dropped a few very silly marks. like the ideal gas equation one. i forgot to divide by 5 at the end which was a little annoying and the conversion of X to Y i messed up. but other than that i feel confident. It was a really nice paper, i just hope Chem 2 is as nice. How did you find it?
oh, i found it really hard, i didnt know how to do atom economy but that was my fault, the mole equations were harder than in past papers and some of the questions were not in the specification.. hopefully unit 2's nicer.
I found it really hard too, harder than the past papers. Even silly ones that I should of known, like the first page with the isotope table, the fact one of the isotopes had a 2- charge totally confused me. Were the amount protons and electrons still the same? Or did the charge only affect the electrons? (Sorry if that makes no sense)
