did anyone got 25.34 degrees celcius for the final temperature of the 2nd question?

25.34 is impossible..( u heat up water just by 0.34 degrees?)

* i got 25.3+ 44.45( cannot remember the exactly value, but it was something like that!)  = 69.8? ( around there)

It was ok. Was pretty angry that we had to write an equation for our chosen chemical (H2SO4) since my teacher told me not to learn those equations. I tried to write the Lead acid battery equation, but I'm not sure if I wrote the right states. I think I got quite a few MC wrong and the Ni/Cd and 0.9V questions.. Did anyone get a blank paper to scan/put up solutions?

You forgot to convert kJ to J, 69.8° is correct

i thought it was pretty easy, but writing the equations for the NiCd fuel cell, screwed me over.

What did people get over the efficiency of the fuel cell over the combustion of hydrogen, near the last question?

Im not that great at chemistry but heres my multiplechoice

CCAC
DCAD
BACA
DCAD
BDDC

anyone else ?

haha mine are so different. i just guessed but. eh, exactly how good would you rate yourself in chem on a scale of 1 to 10? :P

I got the same, you had to convert the kj to j, find the increase then add it to the initial temperature!!

I thought it was very easy considering I did minimal study, but hey I might've just gotten everything wrong :P I was happy walking out though :) Should get around a B/B+...A if I'm lucky :)
For the concentration question in short answer using KA (i've forgotten the chemical, ethanol or something) did you guys end up with 0.35M? :)
