balance this chemical equation:
aqueous solutions of alumininum chloride and sodium carbonate are combined, producing alumininum carbonate
AlCl3(aq) + Na2CO3(aq) ==> Al2(CO3)3 + NaCl
You balance it.
The purpose behind this question and the one you posted just before is to give you practice in going from word equations to symbol equations. You really need to be able to interchange them and not ask for help.
