Chemistry is a piece of cake all advice that i can give is ;
1) be very careful to include state symbols when writing chemical equations especially when stated so in the question.
2) When drawing dot and cross diagrams of atoms remember to put the ions in brackets and write the charge on them i.e [ structure of ion ] charge+-
and remember to show clearly electron belonging to there respective atoms.(don't mix them up )
3)when taking about why a substance conducts electricity mention free or delocalized electrons.
4) HCL IS A COVALENT COMPOUND don't forget it ( i always forget it).
5) always convert cm3 into dm3 when calculating concentration or volume.
6) in electrolysis the +electrode is the anode and the -electrode is the cathode but in the case of a simple cell its the other way around.
7) during electrolysis of CuSO4 with inert electrodes the color of the solution fades.
Other than this there isn't anything i need to be reminded of before the paper .
For physic i have to do lots , so i don't have any good advice but if there is a problem to be solved i would be glad to help.
