i noticed most of u got 1.6V for the galvanic cell question...
But i'm certain u meant to use the 1/2 Cl2 (aq) + e- ---> Cl- 1.4V
rather than the 1/2 Cl2 (g) + e- ---> Cl- 1.36V

Because the Cl2 gas is bubbled into the water, forming aqueous solution. The gas one is used if it a sealed chamber filled with the gas in gaseous states im pretty sure.
So the voltage would be .24 + 1.40 = 1.64V

Im pretty sure actually positive as im looking at a table now that it is 1.60V. 1.64 is not for the gas chlorine.

There goes that 98.

I thought that was a really easy test, but I still didnt know anything.
We had the worst teacher all year, and the whole class went virtually untaught.
But compared to other tests, it was kinda straightforward, some hard calulation questions but, what with the zinc tables and the AAS calulation from that.
If it had been a hard test, I'd have bummed out so terribly.
As it is, maybe i can luck out and get over 70 lol.

for industrial - do you think they'll notice i made up a cationic detergent "Mr Sheens carwash"?
haha i had no idea what to write for that 7 mark question.
i somehow related it back to solvay process and blabbed about that
anyways - good luck to you's all!
Hahah that 7 marker was a bitch. I wrote about env impacts, then guessed at Fabric softners being the ionic detergents, and blabbed what little I knew about that.
