describe how you would fully obtain solid lead 11 carbonate from a mixture of lead 11 carbonate , iron fillings and sodium carbonate.

explain how you would obtain solid lead carbonate from a mixture of lead carbonate and sodium carbonate powder

Is there one problem here or two problems? By the way that is lead (II) carbonat and not lead 11 carbonate.
