Hi, as a GCSE student myself i have found the following site very useful. If you type in Google: Aqa and get on their website, there is a link for past papers. Through this you will find lots of types of paper you need Current GCSE and its pretty straigh forward from there.
You can got to your exam boards site. AQA, OCR or EDEXCEL you can look at past papers there. Hope it helps :)
you can find it on the aqa website
I have also done that gcse paper and I put down copper as the pink brown solid, it might also be worth mentioning that I am one of the best at chemistry in my class
not bbc bitesize there is nothing there!! maths English and science 5 gcse i think:)
The simple answer is that the solid particles of the sugar crystals touch and bump into the water molecules and the water molecules melt the crystals easy as and im only 11! and im already at y11 GCSE level in Chemistry!
The molar heat of combustion of pentanol is 3329 kJ mol-1 according to http://www.creative-chemistry.org.uk/gcse/documents/Module7/N-m07-24.pdf
The number of orbitals is easy. Find out the number of electrons (atomic number) and then separate it into the relevant shells. GCSE: you are required only to know the electron configuration e.g. 2.8.8.... A-Level: sort it into sub-levels 1s, 2s, 2p, 3s, 3p, 4s, 3d.... Ok, so if you are taking the element Mg into consideration GCSE: 2.8.2 A-Level: 3 row down (so 3rd sub-shell) and the s-block of the periodic table 1s2, 2s2, 2p6, 3s2 Finito!
It completely depends on the difficulty level of the paper, to secure a c, I would say you want about 40% or 50% of the paper but it varies.
