Good paper the only hard question was the electrolysis of CuCl apart from that it was all good

agree it was light work

what did yall put for the question about boiling points of group 7??

that as you go up the group the boiling point decreases as the elements at the top of group 7 are the most reactive (fluorine, bromine etc.) I mean that's what I put

for the explanation did you put because as you go down the group there are stronger intermolecular forces and bigger molecules?


and what did yall put for the Avogadro constant question

The number of atoms was 1.505x10 to the 22 or to the 21 (one of the two I can’t quite remember)

did you do the mass * the avocadro?

Hmm. It was because as you go down group 7 the atoms get bigger.
Also they are all diatomic so they form molecules with themselves through covenant bonds which are held together with weak intermolecular forces so they have a low boiling point.
That’s what I wrote I believe it to be correct

here's what I put: DON'T know if it is correct
40g of argon= 1 mole
therefore 1g of argon= 1/40 of a mole
so I did (6.02*10^23)/ 40= 1.505*10^22
my final answer was: 1.505*10^22

well your answer seems better than mine and I hadn't even thought of that (I only wrote what you said for the last 6 mark question)

Nah I talked to my chemistry teacher who got their hands on the paper it is 1.505x10 to the 22
