I'm doing these exams for my sins - my mocks went a lot better than I'd expected, but then last year's papers were quite nice. I wonder what AQA have in store for us...
Can someone explain 4Aiii) Where do they get the 1.63 x 10^-19 in the MS ... it seems as if I'm missing something quite simple out but can't figure out what :/

6B) the table ... How did they get 2V for C-D
Thanks
Haven't got time to do 6B with you right now but you are right about 4aiii . youre missing something very simple. The energies given in the diagram are in eV. You must convert to J to do your calculation. 1J=ev * (1.6x10^19)
