I chose magnesium and zinc. Thought they are the most reactive ones :/

Uh thats definitely not right bcos highest voltage = difference in reactivity highest
Which solution was more concentrated C or D in practical ??

C - because it took more acid therefore it must be more concentrated

The answer was magnesium and copper

But platinum was the least reactive ?
Um it was D because it took less acid, therefore,it was more concentrated ?

I put D but I think it was C because as it is more concentrated, more acid is required to react with all of it. Not sure though.

What did you put for the compounds? People seemed to get different things for the halides
For paper 6 what did you get for the compounds E?
I got copper carbonate.
Some of my mates put iron (ll) carbonate

With sodium hydroxide it formed nothing
With barium nitrate and acid it formed a yellow precipitate (there wasnt anything in ammonia)
