Answer:

I would think so......

Explanation:

And we would represent the equation by.....

#CaCO_3(s) + CuCl_2(aq) rarr CuCO_3(s)darr+ CaCl_2(aq)#

And how would you know whether the reaction would occur? How else but by experiment?

It is a fact that the #K_"sp"# of #"copper carbonate"# is #1.4xx10^-10#. And the #K_"sp"# of #"calcium carbonate"# is #2.8xx10^-9#. And since copper carbonate is more insoluble than calcium carbonate, metathesis would occur, with the result that blue colour of the solution due to #Cu^(2+)# would slowly(?) dissipate.
