I thought the exam went really well the questions I mucked up was the cmdeltaT one, the volume one, the double bond alkane one, and the one where the answer was electrolysis.

I've always been taught to call it a salt bridge, do you think I'll lose any marks for calling it that instead of 'ion bridge'?

I really don't know. Maybe.

For the Heat energy question there were two methods, method A and B. What did you pick and why ?

Method A, Because in B ethanol is lost before being places under the copper can. went something like that
