2016 AQA GCSE Chemistry Unofficial mark scheme 2016

If anyone wants to help filling it out o can remember specific questions, post here

In the first question in the last section, the atom was neon.
(1) Neon has 10 electrons, not 9 (2) The first shell can only hold 2 electrons (3) The outer shell can only hold 8

or something along those lines.

I've got 9 marks estimated so far

Anyone got predictions for grade boundaries?

Question 5b= add hydrogen, nickel catalyst, 60 degress, harderened because high temperature, solid at room temperature.

would this be 5 marks

I got an A in my ISA like 90 UMS How much A's/ A*'s do i need in the exam(s) for an A* overall ?? thnx

Sorry to post this again, but did anybody else put 'steam' and 'high temperatures' for the cracking question? I thought this would be acceptable because it's the other method of cracking?

i put high temperature and catalyst for n1 and high temperature and steam for number 2

yeah but neon has 10 it said it was in the same row as lithium

It was just the nucleus, because it said about part 'Z', and that's all it wanted, not the whole atom. The way you have written the answer doesn't make it very clear though, it should be something like this

Protons (+1)
Neutrons (0)

I reckon i've got 54-55 with harsh marking. By the way 20.3 is a wrong answer! You are meant to place it in 2 decimal figures (from the graph) for 2 marks. So in reality the answer is 20.30 not 20.3. How do I know this? 1) It was a 2 marker. 2) Our teacher is an AQA part time examiner and that is what he told us.
