# How do we represent the formation of copper carbonate from copper chloride and sodium carbonate?

$C u C {l}_{2} \left(a q\right) + N {a}_{2} C {O}_{3} \left(a q\right) \rightarrow C u C {O}_{3} \left(s\right) \downarrow + 2 N a C l \left(a q\right)$
This is a metathesis reaction.....and copper carbonate is reasonably obscure, and what we would probably isolate is $C {u}_{2} C {O}_{3} {\left(O H\right)}_{2}$.....(this occurs naturally as the mineral $\text{malachite}$).
$C u C {l}_{2}$ $\left(a q\right)$ $+$ $N {a}_{2} C {O}_{3}$$\left(a q\right)$ ------------> $2 N a C l \left(a q\right) + C u C {l}_{3} \left(s\right)$
