Exam thoughts? Easy? Hard?
Weird flex, but okWas pretty straightforward tbh, the 7 markers for both core and option (Forensic at least) were kinda vague but it was alright on the whole.
Yeah that's correctwhen they said chromatography, did they want to compare all the different types or just the princples and applications behind them. I dicussed liquid chromatography in detail but just gave a few references to the other types eg.gas, but didn't go in extreme detail about all of them.
Anyone get 0.02 grams for glucose?
It's for forensic analysis so HPLC and GLCwhen they said chromatography, did they want to compare all the different types or just the princples and applications behind them.

88 degreesWhat did people get for the final temperature of the water? I got 90 something degrees, but really have no idea if I got it right
Do you wanna explain why the efficiency is 38% and not 40%?88 degrees
Efficiency would depend on the value you got from your graph. But for every 20% drop in efficiency there was a 5mm increase in distance. So every 0.25mm =1% decrease, so for 3mm (45-48), = 12% drop so 50-12=38%.Do you wanna explain why the efficiency is 38% and not 40%?
Hmm, well idk I'll probably only lose 1 mark, I don't mind c:Efficiency would depend on the value you got from your graph. But for every 20% drop in efficiency there was a 5mm increase in distance. So every 0.25mm =1% decrease, so for 3mm (45-48), = 12% drop so 50-12=38%.
Although my distance value for the graph was 48.2mm so idk if they’ll except that.
