The first one is an example my teacher gave me, but even with that help i have no idea what to do, appreciate any kind of help that can be given, my report is due for tomorrow(well, today since is 01:45 AM) and all i have left to do is that.

Thanks in advance, cheers from Brazil, i hope my english is understandable.

Most likely these equations are intended to test your knowledge about reactivity series, but either you copied them wrong, or they were wrong as given to you. No such thing as Cu(CO₃)₂, in the first reaction NO₂ shows up on the right from nowhere and so on.
