Mg (s)+ CuSO4(aq)=MgSO4(aq) + Cu(s) and Pb(s)+ 2AgNO3(aq)=Pb(NO3)2 (aq)+2Ag(s)

CuBr2 : if Br is a million- and there are 2 with the Cu, Cu must be 2+ to have a internet 0 cost. So interior the reaction the Ca can replace the Cu. Polyatomic ions: the checklist is short, memorize it! Sorry.

Cu + 2 AgNO3 --> Cu(NO3)2 + 2 Ag
2Fe + 3 CuCl2 --> 2 FeCl3 + 3 Cu

Pb(NO3)2+ Zn --> Zn(NO3)2+Pb.
The metal formed (lead) is grey.
CuSO4+Mg -->MgSO4 +Cu.
Copper(ll)Sulphate is blue in colour, magnesium is grey in colour and the metal formed(copper) is reddish brown.Hope that this helps.
