Yeah, I get you but the 45 or whatever was the same time it took for the lower concentration...so I excluded it. Harsh but then thats the new spec for ya
Ah well :/ how many marks was that Q?

Elements heavier than iron are produced at the end of a massive star's life cycle and released in a supernova and elements up to iron are produced at the end of a star's life cycle.Elements lighter than iron are produced when the star is stable.Thats how I think it goes.
Ah yeah, thanks mate! Just read spec all it says is:

Candidates should know that elements up to Iron are produced during the stable period of a star. Elements heavier than iron are formed in a supernova.

One of the questions was about adding excess water to anhydrous copper sulfate, i said it was exothermic, isn't that correct? Everyone keeps saying it was endothermic and im pretty sure the reaction is exothermic.

For the three marker on the sodium and iodine I put:
Sodium loses a electron to get a positive charge
Iodine gains a electron to get a negative charge
Due to separate charges they are attracted to each other (Opposite charges attract)
This involves electrons in the outermost shell


What did you get on the question about the furnace?

BTW is anyone going to make a unofficial mark scheme?

The test was okay today actually, the six mark question was a nice one as all the information was there. Oh and nobody in my school managed to work out the empiracal formula, I got N (1) Cu(3)? Anyone else get that? The first question was quite tricky too...?

exothermic because the opposite reaction took in energy and it was 300J because the energy took in has to be balanced by the energy released in the exothermic reaction.

You can check what I wrote above but yeah I meant the iodine question, I drew the diagram for Na+1 but not Fe-1 because I was too stupid to think and just draw the other shell >: can I get the 3marks for what I wrote above?
You can definitely get 3 marks for that question, provided you had a detailed enough answer - the diagram was optional.

Same answer for both.
Also on the 300J one I got 300J but I also wrote 300J are transfered to the surrounding usually in the form of heat
or something like that I took some of the wording from the answer as it was two marks

(Original post by MajorRisk)
Yeah was 300J

Exactly waht i put, don't know why I was listening to those idiots saying it was endothermic.
