AQA GCSE Chemistry Exam Unit 1 (C1) 15th June 2012 (New Spec.)

On the first page, what did you write for the question about why atoms have no overall charge...

I wrote the number of protons equals the number of neutrons therefore the atom has no overall charge...? dont know if its right...

No, it was number of protons and electrons, the neutrons are neutral

I'm guessing 46/60?
I find Chemistry really easy and I revised like hell....but this exam - stupidly hard!
The exam was all really applying knowledge but the questions were hard and badly worded.
I found biology much easier.

Last question I put the boiling points were so similar of Oxygen and Argon so they are hard to separate. What did people get for the QWR question 3 about poly(ethene)??

I put that too, i think it's right

I put the same for oxygen and argon, nobody else seems to have though!
I didn't have time to finish the poly(ethene) question, it was the only one I didn't finish

It was electrons, got confused
meant
number of protons = number of electrons

This was the worst exam I've ever done in my life! I was resitting it from January when I got a U but I doubt I've done any better at all. Hopefully they'll lower the grade boundaries. I think I gave up after the 5th set of questions and I was crying afterwards!

for the poly(ethane) For advantages i put they are strong and make the supermarket money because they charge for them for disadvantages i put that they normally only get used once and they end up in landfill, have i got any of them right?

i out more disadvantages but i can't remember

I'm guessing 46/60?

Bags are biodegradable, that should've an advantage I think??

i put the boiling points of oxygen and nitrogen are so similar so they are hard to separate! are you sure it's oxygen and argon? some of my friends said because they are not a noble gas.. which is right?

also , what did you write for the density question of nitrogen? and the graph calculation?

what can you see when fermentation between sugar solution and yeast?

the question was when clay and calcium carbonate are heated in the rotary kiln, and methane and air are put in, which two gases would be produced most?

I put Carbon Dioxide, as that's what's produced when calcium carbonate decomposes, and I also guessed Nitrogen, because it makes up the majority of the air going in, but that's probably wrong.
