Chemistry Paper 1 + Mark Scheme Here
Fibonacci:
Hey people. I am waiting on more papers. I'll get the Physics and economics Paper 1 tomorrow. Biology paper 1, i'll only get like on Tuesday 'cause my teacher is currently out.
By the way, there is a lil' problem with the mark scheme I posted. Question 26 isn't C, but in fact, it's A. My teacher mis read the question. If it had been talking about the compound (metal E sulphate), then it would be C. We know it's a transition metal because the compound is coloured and if it is a compound, it would have a low density. But the question only asks for the element E, therefore, the transition metal. So, as said in the syllabus, it's got a high density and high melting point. Sorry about that.
That said, I got 39/40 :D
See Ya,
Peace

but in the marking scheme you posted the answer for question 26 is A so there is no mistake in the marking scheme bro ;)
and ya its green and hence its iron (II) (the percipitate of iron (II) is green) and its a transition metal so it has high melting point aswell as high density. ;D
congrats on getting the extra mark were both 39/40 now 8)

thanks so much mate-I put aqueous cryolite instead of molten and also put petrol instead of paraffin-so 38/40 for me! :D
Great job-plus rep^^

I can't :P. Molten cryolite is used of the electrolysis of aluminium and fuel for aircrats is parafin. Sorry :p
By the way, already got Physics and Eco p1. will be posting today
