okay first thanks

second Im not understanding the dilution of coloured solutions to prove that their are moving particles

Third I'm having a problem with writing equations like when it says eg sulfric acid write it in symbolic form.

until now these are my issues but i have alot
so if u dnt mind ill tell you in a few hours or so

thank you for helping

Also do you have a good revision site at the moment I'm usin Edexcel IGCSE chemistry by Cliff Curtis is it any good

we learnt stuff for igcse chem last year but this year the school changed it and now were doing edexcel 360 gcse chem but most of my notes are for igcse so they're over detailed on some topics and have stuff we don't need anymore. i hate my school for changing -.-

yeah because it includes part of the A-level course as well or something apparently. But to be honest, if you take A-level Chemistry- you will be at advantage as you'd already have learnt a bit of it. I'm definitely taking Chemistry next year so I wouldn't have minded staying on IGCSE.

1.4 describe simple experiments leading to the idea of the small size of particles and their
movement including:
i dilution of coloured solutions

1.19 understand the term molar volume of a gas and use its values (24 dm3 and
24,000 cm3) at room temperature and pressure (rtp) in calculations.

1.21 use the state symbols (s), (l), (g) and (aq) in chemical equations to represent solids,
liquids, gases and aqueous solutions respectively (Do i hve 2 learn them)

ok all you really need to know for calculations volume=mass x 24000.
thats because 1 mole of gas is 24000cm^3. as long as you know how to rearange the formulae thats all you need to know

yes you do have to learn them. right for that all you need to do is learn the table on page 71 of your cliff curtis revision guide. its the one just under solubility of salts.
a (s) would be insoluble salts. (aq) would be the soluble salts in an equation. (l) would be liquids such as water and (g) would just be gasses like carbondioxide ect.
