hi Cher for planning I said fe3+ is more reactive than Fe2+, and I assumed that I had 2 samples of iron because the planning stated to assume I had all the apparatus n stuff I needed.. Is it ok if I said that if it's fe3+, more copper wld be produced in 2 minutes compared to fe2+?

monkey :
Cher, for planning, I wrote, measure mass of copper, find mole, then find moles of iron and do mole ratio, see if ratio is 1:1 or 2:3

hi cher if my graph intersection point value was very far off the answer of 27.0, will my table of values or graph be penalised for it? (and for error carried forward part, if I got the rest of the mole calculation right, I would still be given full credit right?)

Will they penalise for not writing + in the table for temp change

hi :
cher i misread value (it was supp to be 27.5 but i wrote 25.5) from my graph and used it to calculate to moles and stuff… will i have ecf 🙏

Wait why cannot pass thru origin? I did a few school papers with those question they state u should pass thru origin

cher do we need to the circle last two points on the graph which was decreasing when its supposed to be increasing cos they said to circle any anomalies

what if i extrapolated the graphs until it goes through the origin? also how much marks are deducted for ECF
