Post by: sabrina on May 29, 2010, 11:24:19 am
hi
ur notes are awesome but there is a mistake in ur equilibrium notes where when increase in pressure will favors forward reaction but there r 4 moles in reactant not 3 moles
Title: Re: Chemistry AS notes
Post by: sabrina on May 29, 2010, 11:43:19 am
hi
in ur notes on period 3 the melting point of Si is wrong. Si have high melting point than aluminum
Title: Re: Chemistry AS notes
Post by: sabrina on May 29, 2010, 11:45:58 am
hi
also sulfur's melting point is a bit higher than phosphorous  due to more wan der waals forces

just one thing...the stuff about period 3 melting boiling points and that, is that unit 2??
Also this is edexcel right? do we need to know the 'how science works' boxes do you think????

would it be wise to do the past papers all again.? I mean i've already done them. i got to prepare for p5 also...which i don't know anything about plz..give me some notes for it!! plzz help..
Title: Re: Chemistry AS notes
Post by: Meticulous on May 30, 2010, 01:32:58 pm
Yes. You should do the past papers again, but try focusing on the most recent. And don't just do the. STUDY THEM. Look at the hard questions, expect the worst, you know what I mean? For p5---> PAST PAPERS
Title: Re: Chemistry AS notes
