Explanation:

Step1: Write the balanced formula equation

When \(HNO_3(aq)\) reacts with \(Ga(OH)_3(s)\), it is an acid - base reaction. The general form of an acid - base reaction is \(acid+base = salt + water\).
The reaction is \(3HNO_3(aq)+Ga(OH)_3(s)=Ga(NO_3)_3(aq)+3H_2O(l)\)

Step2: Write the complete ionic equation

\(HNO_3\) is a strong acid and dissociates completely: \(HNO_3(aq)=H^{+}(aq)+NO_3^{-}(aq)\)
\(Ga(NO_3)_3\) is a soluble salt and dissociates: \(Ga(NO_3)_3(aq)=Ga^{3 +}(aq)+3NO_3^{-}(aq)\)
\(H_2O\) is a weak electrolyte and does not dissociate significantly.
The complete ionic equation is \(3H^{+}(aq)+3NO_3^{-}(aq)+Ga(OH)_3(s)=Ga^{3 +}(aq)+3NO_3^{-}(aq)+3H_2O(l)\)

Step3: Write the net ionic equation

Cancel out the spectator ions (\(NO_3^{-}\) in this case)
The net ionic equation is \(3H^{+}(aq)+Ga(OH)_3(s)=Ga^{3 +}(aq)+3H_2O(l)\)

Answer:

• Balanced formula equation: \(3HNO_3(aq)+Ga(OH)_3(s)=Ga(NO_3)_3(aq)+3H_2O(l)\)
• Complete ionic equation: \(3H^{+}(aq)+3NO_3^{-}(aq)+Ga(OH)_3(s)=Ga^{3 +}(aq)+3NO_3^{-}(aq)+3H_2O(l)\)
• Net ionic equation: \(3H^{+}(aq)+Ga(OH)_3(s)=Ga^{3 +}(aq)+3H_2O(l)\)
