sadly you used the final temperature as opposed to the peak temperature, which would have given you a temperature change of 20 degrees. It would have been 55*4.2*20 :/

would I get marks for putting the names of the elements instead of their symbols for the first page of C3??

Ooopss I did the same thing we should get the marks because symbol/name is the same thing however I'm. Sure they didn't specifically ask for the symbols did they?

I think it was regarding Ionic Bonding between two molecules (question recurrent on all papers). However alot of the answers need to be specific hence why you need to review past papers.

I have a question I'm confused on so it says: give one ethical reason why iodine should NOT be added to sodium chloride and used in food. I'm confused because I googled it and it says that iodine is added to salt please help
