Answer #1

In double displacement reactions the ions exchange their cation/anion partners to form new products.

Ex - ZnS + 2HCl -> ZnCl2 + H2S

Here in this case we have

chromium (III) nitrate Cr(NO3)3

ammonium carbonate (NH4)2CO3

as reactants when they are involved in reaction the following chemical reaction takes place -

2Cr(NO3)3 +3 (NH4)2CO3 ------> 6NH4NO3 + Cr2(CO3)3

the molecular formula of the product containing chromium (III) ion is Cr2(CO3)3

and the molecular formula of the product containing ammonium ion is NH4NO3
