when aqueous solutions of sodium carbonate and manganese(V) chloride are mixed, a precipitate forms. The precipitate is a compound containing manganese.

I have to write the chemical, complete ionic, and net ionic equations for it.

I will be happy to critique your thinking on this.
Well i think the chemical equation is Na2CO3 + MnCL5 --> NaCl + Mn2(CO3)5

complete ionic:
Na^+ + CO3^2- + Mn^5+ + Cl- --> Na^+ + Cl- + Mn2(CO3)5

net ionic:
CO3^2- + Mn^5+ --> Mn2(CO3)5

Frankly, I doubt that MnCl5 exists.
