Please can someone help balance and form this equation (it is wrong so far)!!!

Cl3CrH12O6 + H20 + CO(NH2)2 + C5H8O2 = C15H21CrO6 + ...

Look here:

Urea hydrolysis to ammonia and carbondioxide

(NH2)2CO + H2O => 2 NH3 + CO2

Acetylacetone and ammonia give pentandionate and ammonium

CH3COCH2COCH3 + NH3 => CH3COCH2COCH2- + NH4+

The pentandionate react with the chromium-III

3 CH3COCH2COCH2- + Cr 3+ => (CH3COCH2COCH2)Cr
