is n2 and o2- isolectric or something like that
Na+ and 02- Yeah they are... I guessed and said this one was false.. FAIL
Pisstake is that as a joke before the exam, someone said anyone know what isoelectronic is and we were all like lolshup dont need to know that.

on the electrophilic addition one with HBr you didn't have to write electrophilic addition did you?? it was just a drawing one??
well i just drew it since they'd given us a huge white space!

I wrote for the graph question that..

The biggest peak was the noble gas = least reactive (C)
Then the group 3 element = 3 elements after highest peak (D)
The 5p electrons was the element just before the noble gas (B) since its a halogen in period 2
Dont remember what A was

The question after was that was Ca2+

The identifying the alkene was Z-pent-2ene or something.

For organic question I put. Hydrogen and Platinum at RTP, 1,2-dibromoethane.

Then I did purple to brown, cuz off stupid George Facer

I also got 4000ppm. Drew the electrophilic addition of hydrogen bromide with ethene.

For the risk question, I was sooo screwed I didnt know what to say so I wrote. One point about fume cupboard, so hopefully ill get 2 marks

And the last question about the other 2 factors, I said somethin about how Polystrene is non-biodegradable and that paper cups can be recycled.

For the entalphy one, I think I didnt times by two for the first one, so my 2nd one was bigger .. But for two mistakes I wrote heat loss and incomplete combustion.

Cracking I wrote when long chain alkanes get broken down into a lot of smaller chained alkanes. Just wrote Oil before that .

Also the polymer question was c-c-c-c. the two c2h6groups and the rest with h.

Thats all I remember on top of my head, just remind me off the other question, see if I can help .

I think it was the answer above that. something like a carbon-carbon double bond is double the strenghth of a single bond < that's incorrect
nah that was another question

D or A(whichever one was slightly covalent), I put D because Li has higher charge density than like Na. But now I think of it, its only a 1+ ion, so wouldnt be able to polarise that much so its probably A. But come onnn, Iodine is friggin hyyuggge compared to Lithium.

lool i think that would probably depend on the book but the effect is still the same, i think the main thing is showing that it goes from purple to a lighter shade
