Finding net ionic equation of K2CO3 and CaCl2?

The choices are

a) 2K (aq) + CO3^-2 (aq) K2CO3(aq)

b) 2K (aq) + 2Cl (aq) 2KCl (aq)

c) K (aq) + 2Cl (aq) KCl (aq)

d) Ca (aq) + CO3^-2 (aq) CaCO3 (s)

e) K2CO3 (aq) + CaCl2 2KCl (aq) + CaCO3 (s)

I think it is either B or E , but i am leaning towards E.

Suggestion?

Thanks.

    Chemical equation:

    K2CO3 (aq) + CaCl2 (aq) –> 2KCl (aq) + CaCO3 (s)

    Total ionic equation:

    2K+ (aq) + CO3^2- (aq) + Ca2+ (aq) + 2Cl- (aq) –> 2K+ (aq) + 2Cl- (aq) + CaCO3 (s)

    Net ionic equation:

    CO3^2- (aq) + Ca2+ (aq) –> CaCO3 (s)

    Answer: D

    Balanced reaction is good. It is a double replacement. To write the net ionic equation you have to break apart the equation. Assuming that none of the reactants or products are aqueous, the net ionic equation would be the same as the balanced reaction.

    1) Yes this is a double replacement reaction. The cations and anions swap. 2) Write out the total ionic equation and cancel anything that is common on both sides Ca+2(aq) + 2Cl-(aq) + 2Na+(aq) + CO3-2(aq) –> CaCO3(s) + 2Na+(aq) + 2Cl-(aq) so the net ionic equation becomes: Ca+2(aq) + CO3-2(aq) –> CaCO3(s)
