Question

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

Answer 1

`CuCl_2(aq) + Na_2CO_3(aq) rarr CuCO_3(s)darr + 2NaCl(aq)`

Explanation:

This is a metathesis reaction.....and copper carbonate is reasonably obscure, and what we would probably isolate is `Cu_2CO_3(OH)_2`.....(this occurs naturally as the mineral `"malachite"`).

Answer 2

`CuCl_2` `(aq)` `+` `Na_2CO_3` `(aq)` ------------> `2NaCl(aq) + CuCl_3(s)`
