I think you should read properly.Really? I didn't read that anywhere:/ FML
I can't remember which one I put!! Acid or carbonate??? I remember choosing carbonate first and then thinking it was acid but now I can't remember if I changed it... Oh well it is over and I just have to worry about maths, geo and history!!!I said acid was solution, because I remember calcium carbonate being a powder. =D And at that time, i was guessing between acid + metal and acid+carbonate.
