I think the paper went very well, I have a question though about two questions which confused me only slightly ...
One was the energy density one, I put 47,000. That threw me off because it asked for 2 sig. fig. and with a number that big I was doubting myself whether I did it the right way.
Another one, which asked you about calculating enthalpy changes in a combustion reaction ... asking what other piece of information was needed to calculate it ..... I put something like "The mass of Hydrocarbon A that was burnt / used in the combustion reaction" .... other people were talking about Identifying the starting mass and final mass ... would I have got the mark for that question though?
Looking at this thread though and talking to my teacher I think that is all that bothered me. So I think I have potentially lost 2-3 marks.
