Yep! Because 75% was the new isotope after 8 days so after 4 days it would have been 50%. smile.gif

Yeah it was four people were saying it was 8 but there is no way they would give you the answer in the question.

shit i wrote down 2

what did people write for the question in the second part on

describe how the ester would be heated? (or something like that)

it was for 1 mark i wrote it would be heated in a water bath with concentrated sulphuric acid catalyst. Is that ok?

I'm sure that would be fine. It was only for one mark and they didn't ask for a diagram. I didn't mention the concentrated H2SO4 but hopefully I will still get the mark.
I think there's about 12 marks in Paper 2 that I know I've got wrong. The number I've got wrong that I don't know about is a mystery! But hopefully that number is minimal!

What did everyone get for that question about the electrolyte in Q14. It gave you the densities and melting points of the metal and its chloride and asked what form the metal would be in and where it would occur on the electrolyte. I put it was a liquid and would occur on the surface of the electrolyte but I think it might have been on the bottom of the electrolyte because of the higher density? Anyone remember?

I said as a liquid at the bottom because it had a greater density but a lower melting point.

But it had a higher density so how could it be on the surface?
