Question

What is the net ionic equation for the reaction of aqueous nickel(II) acetate and aqueous sodium carbonate?

A. Ni2+(aq) + CO32–(aq) → NiCO3(s)
B. Na+(aq) + CH3CO2–(aq) → NaCH3CO2(s)
C. Ni2+(aq) + 2 CH3CO2–(aq) → Ni(CH3CO2)2(s)
D. 2 Ni2+(aq) + CO32–(aq) → NiCO3(s)
E. Ni2+(aq) + 2 Na+(aq) → NiNa2(s)

Answer 1

A. Ni²⁺(aq) + CO₃^2- (aq) $\to$ NiCO₃(s)
