Question

write the balanced net ionic equation for the reaction when na₂s and niso₄ are mixed in aqueous solution. if no reaction occurs, simply write only nr. be sure to include the proper phases for all species within the reaction.

Explanation:

Step1: Write the molecular equation

When \(Na_2S\) and \(NiSO_4\) are mixed, the molecular equation is \(Na_{2}S(aq)+NiSO_{4}(aq)=Na_{2}SO_{4}(aq)+NiS(s)\)

Step2: Write the total ionic equation

The total ionic equation: \(2Na^{+}(aq)+S^{2 -}(aq)+Ni^{2+}(aq)+SO_{4}^{2 -}(aq)=2Na^{+}(aq)+SO_{4}^{2 -}(aq)+NiS(s)\)

Step3: Write the net ionic equation

Cancel out the spectator ions (\(Na^{+}\) and \(SO_{4}^{2 -}\)). The net ionic equation is \(Ni^{2+}(aq)+S^{2 -}(aq)=NiS(s)\)

Answer:

\(Ni^{2+}(aq)+S^{2 -}(aq)=NiS(s)\)
