Need results for prac. dot point (1 Viewer)

[Affinity]

I lost my results for two pracs
can anyone tell me their results please?

solve problems, plan and perform
a first-hand investigation to carry
out the fermentation of glucose
and monitor mass changes

identify data sources, choose
resources and perform a first-hand
investigation to determine and
compare heats of combustion of
at least three liquid alkanols per
gram and per mole

Why don't you just do the pracs again?
If you really want I can give you MY results for the Fermentation but the Alkanols prac - even though it was meant to be handed in half a year ago - is just the mass and time changes.

hmm it's not quite possible to do the prac again at our school, teachers and the lab assistant do not trust students

fermentation - in 100ml of water
day weight inc flask(g)
0 214.1
1 208.8
2 208.0
3 207.5
4 207.5

combustion of alkanols <---- crap results, shitty calorimeter, 40-55% error lol
temp change = 10C
fuel weight(b4)(g) weight(after)(g)
Ethanol 142.68 142.22
1-Butanol 148.28 147.75
2-Propanol 134.60 134.14

i dont'' think you need to memorise results... (?????)
isn't it the procedure that's most important? (and if the question's nasty, you can make up a value for the results and account for the discrepancy as 'experimental error' eheh... -.-;;

yeah i doubt you need to meomorise results. its more important you know what the results represent
