Answer 1

The molecular equation for the reaction of aqueous sodium carbonate (Na2CO3) and aqueous nickel(II) chloride (NiCl2) shows no reaction in aqueous solution, as sodium carbonate does not form a precipitate with nickel(II) chloride.

Step-by-step explanation:

The student's question asks for the molecular and the net ionic equations for the reaction of aqueous sodium carbonate (Na2CO3) and aqueous nickel(II) chloride (NiCl2). To write the molecular equation, we first write out the formulas with their respective states:

Na2CO3(aq) + NiCl2(aq) → NiCO3(s) + 2NaCl(aq)

However, since Na2CO3 does not form a precipitate with NiCl2, they remain in solution. Therefore, the net ionic equation is not needed as there is no reaction between these two compounds in aqueous solution.
