The reaction is tentative.........

Cr_2(SO_4)_3(aq) + 3(NH_4)_2CO_3(aq)rarr (NH_4)_2SO_4(aq)+Cr_2(CO_3)_3(s)darr

Explanation:

A. 2Cr^(3+) + 3CO_3^(2-) rarr Cr_2(CO_3)_3(s)darr is the net ionic equation.

B. The spectator ions are "ammonium ion", NH_4^+, and "sulfate ion", SO_4^(2-), which do not take part in the reaction, and remain in aqueous solution.
