I don't think you'd need the whole experiment - it said PROCEDURE to undertake. It was also only 2 marks, so it's doubtful you'd need to have included accuracy/validity to gain full marks.
uh? You have the order of the equations around the wrong way.
At anode, H2O + e --> 1/2H2 + OH
At cathode, H2O --> 1/2O2 + 2H + 2e. (this equation was lower down - the 1.23V one)
Re: second part, yeah. Electrolytic require energy input, galvanic are spontaneous and produce energy.
If anyone's interested I've uploaded the MC question sheet in the thread below. It's upside down and crap quality because I tried to scan it quickly - but you'll live. Enjoy. :)
Here you go. It's got some of my scribbling on it (sorry) - I tried to rub out some of the stuff I did in pencil. Sorry again it's upside down.. and the quality is crap because I tried to do it quickly. Ah well, at least you can still see the questions.
This is all I'm gonna upload, too lazy to...
Um I'll upload the MC (the things I do to procrastinate physics study), but I can't upload the short answer questions because (obviously) I wouldn't have been able to take it home. The MC has some of my scribbling on it though. Apologies its not clean. :(
And I seriously cbf for the rest of the...
I'm going to estimate around ~75. Lost about 3 marks in MC and stuffed up some calc questions. Estimating conservatively because I think they mark very strictly with the criteria.. fingers crossed for a low-mid band 6.
Why? the question specifically said modelling. And theres a specific dotpoint which says you have to *model* an equilibrium reaction. If they wanted the prac, they would've said so.
There are no methyl chains. When you name carbon compounds, you take the longest C chain - in each case its still 3 so its always gonna be something propane.
