Took me a while to make so any rep would be much appreciated :smile:. I hope this helped you all, I was getting impatient with it not being made in time so I made my own.

Edit: not going to be adding or changing anything at this point. Remember it is UNOFFICIAL.

aluminium oxide


That's the catalyst, yes, but I think you just needed to mention the presence of an aluminium oxide catalyst.

You can get the ones from my thread if you like
Question 5b= add hydrogen, nickel catalyst, 60 degress, harderened because high temperature, solid at room temperature.

would this be 5 marks
1)
Draw the diagram - 2 on the inner shell, 3 on the outershell
a) i) Proton, Neutrons - Neutrons neutral charge, Protons +1 charge (mis-read and wrote about electrons :frown: )
a) ii) Got 8 on its outer shell, doesen't have 1 blah blah.

2) a) i0 20.3

Black - incomplete combustion/zoot C
Hexane - more flammable, less smoke, and it produced more energy.

3) Thermal decomposition, Copper Oxide
