I would think so......

Explanation:

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

$C a C O_{3} (s) + C u C l_{2} (a q) \to C u C O_{3} (s) ⏐ ↓ + C a C l_{2} (a q)$ $CaCO_3(s) + CuCl_2(aq) rarr CuCO_3(s)darr+ CaCl_2(aq)$

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

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