I plotted the mass of CuO on the y-axis against the mass of the basic carbonate on the x-axis. Now the 2 values to calculate the gradient are 5.70g (basic carbonate, x-axis) and 4.00g (CuO, y-axis). So how exactly do we use these numbers to calculate x ?
Appreciate any help.

Anyone?
I also have a question in the October November 2009 paper: question 1 (d) (table), I found it really confusing, and the ms didnt help a lot. Can someone explain?

Ionic Bonding Poem - a snippet of chemical poetry
(anon Y11 student, Whitby Community College, Oct 31st 2002)
How do I long for a full outer shell!
being chlorine having seven, is a horrid hell
but my name is sodium and I have one spare!
I want to lose it, can we not share?
No? for are we not a perfect match
chuck it to me, I promise to catch
then we can live our separate ways
and live with full shells to the end of our days!
and so our tale comes to an end
as positive and negative we shall remain friends
