The metal which can displace the Zn from its aqueous solution is Ca,K,Na.
And a metal which can't do it is Fe, Sn, Pb.
When the limestone is strongly heated it turns into CaO.
It is an decomposition reaction.
Plz mark as brainlist if it helps.

Metal which can displace is aluminium and which can't displace is Iron.
Limestone is nothing but calcium carbonate
CaCo3-----> CaO + CO2
It is a decomposition reaction
Hope it helps
