hey i'm takin Chem. paper 5 this wed. !
The question 2 (table) is a real workout for the fingers!! Ain't it just a bunch of useless calculations?? Whats the examiner testing...our ability to do 10 odd subtractions quick and accurately??
Who thinks its annoying??
So, how do u decide which useful columns to use??
Like in May/june 2009 paper 5
Ques2 a)how to decide what to calc. in E, F, G & H columns?
I have done this
E: mass of solution/g (C-B)
F: mass of solid /g (D-B)
G: mass of water evaporated /g (C-D)
Are these enough to analyse the data & plot the graph?
what is needed & what is not needed?? Do all columns need to be filled?
lets just open another topic for this paper...i need some help in it!
