write chemical, complete ionic and net ionic equations for the reaction between CaCl2 and NaCO3

Question

I cannot figure it out, although i think that it has something to do with a double replacement reaction.

Answer 1

I'll assume you meant Na₂CO₃ and NaCO₃ does not exist.  That being the case, you would have...

Chemical:  CaCl₂(aq) + Na₂CO₃(aq) ==> CaCO₃(s) + 2NaCl(aq)

Ionic:  Ca²⁺(aq) + 2Cl^-(aq) + 2Na⁺(aq) + CO₃^2-(aq) ==> CaCO₃(s) + 2Na⁺(aq) + 2Cl^-(aq)

Net ionic:  Ca²⁺(aq) + CO₃^2-(aq) ==> CaCO₃(s)  The Na⁺ and Cl^- are spectator ions.
