hey guys
I found this paper fairly straight forward
UNTIL
I found out that I did a mistake on the last question
the Fe2+, Fe3+ and Pb galvanic cell question,,
I put Pb2+ reduced to Pb, and Fe oxidised to Fe2+
Which are WRONG.
there are 3 marks for writing half-equations
1mark for calculating potential electrode
3marks for filling the blanks of the cell diagram
so if I did the first question wrong.
WHOLE thing will be marked wrong also??
7marks deducted straight away from me?
or will i still get marks for error-carrying??
gosh im so upset now
