I am panicking as Paper 6 chem is slowly approaching..I seem to have forgotten lots of stuff, and I need some tips and hints in solving paper 6 without going into unnecessary items which come only in paper3,etc
I'm also wondering if anyone got a link to a page which shows all lab apparatus labeled because in lots of papers there is questions on labeling them.
Help really appreciated, thanks in advance. :) :) :)

Simply plot the points and join them freely..

points either have to be circled or you can use a cross(X)

What's the difficulty?

And whenever you draw a graph

Remember SLAP

Label
Axis

I already revised the lab apparatus and the experiements. The only thing i don't know are the tests, does anyone know which chapter they are or better yet what is the chapter which needs to be the most focused one for tests? Also thanks, and good luck.

Don't worry people, its just P6 and its only for 20% so yeah.

aw i meant the questions

the larger magnesium and iron powder

With magnesium pieces initial rate of reaction will be much lower, but it will plateau out on the same(over a longer period of time)

With iron powder, it will be still lower, since iron is less reactive as compared to zinc and magnesium, it too will plateau out on the same level, but initial reaction will be much slower
