    With balancing equations I found that it helps if you write down the amount of elements at each side of the equation before attempting to balance them

    Aaah I see, I did AQA Chemistry in Year 10 and achieved an A*

    Mind providing an example you struggle with on Balancing Equations?

    What do you mean by Mixing Different Atoms? Displacement reactions?

    Chemistry is not about remembering facts, if you understand it properly then you shouldn't need to memorise very much at all

    Right paper chromatography is where you put a line (with pencil so it doesn't deprecate the colours) and put for dot of food dye (or something like that) along that pencil line. When you the put this in water the different pigments in the die will separate by mass the heavy pigments will stay near the pencil line where as the lighter pigments will travel up with the water. I might of explained that badly

    How the Exam went?
    Well, it went fine to be honest. The questions were fairly easy it was basic knownledge tbh.
    I know I definatly didn't get a D+, because I got over 14.
    I probably got a C+ or a B-
    My teacher is a generous marker so if i'm one mark away he'll give me the grade above. There was one rfm question I know I got it right. There was a percentage yield question at the end that was simple. I'm starting to like Chemistry, I appreciate every bit of help once again thanks!
