On the balancing equations question I put 4,2,4 for some reason instead of 2,1,2, would I still get it or does it need to be in simplest form?


Ill think they allow it
For some stupid reason i wrote 2,2,2
Would filtration be ok for the first C3 question? And in C2 for the percentage yield question I put not all the reactants may have reacted, would that be accepted??

read what i said again through LOL, i was thinking there are already electrical cars existing so hydrogen fuel cant produce electric energy, open eyes you gayfgt.

The answer was electrical energy

Don't worry too much, it was just a 1 marker :wink: I found the 1 markers more challenging than most of the 3-4 markers in the Chem papers


Haha yeah :smile:. This is exactly me, in papers I never really find the longer questions that obscure and hard to answer, it's just those little 1 markers that they throw in there :tongue:

Filtration + Chlorination

That should also get you the mark, I put the reaction did not reach completion, both along the same lines :smile:
What was the answer to the potassium and acid question about why the student shouldn't react them ?

Yes I got that! :biggrin:
The reaction can never reach completion? It's reversible?

I think you need to say that the number of protons increase


good, i put that too :smile::smile:

Potassium is very reactive so putting them together would mean a vigorous and potentially harmful reaction would occur

Essentially comes down to...

Potassium is VERYYYYYYYYY reactive.

Pad that out a bit, add words like "vigarous" and "dangerous" and you have your two mark answer!

I can't really remember the questions enough to debate, I may have dropped a mark there but at the time it seemed right so I'm not sure

I put that the periodic table is order by the number of protons in an atom ascendingly

AHH **** I wrote that it is very reactive so high temperatures will be required/ specific conditions which will be expensive... Help do I get any marks for this **** oh godness

Only if its on the mark scheme :cool:
Seriously chemistry was ridiculous and i seem to be the only one:frown:

Yh I think you'll get a mark for saying it is very reactive
