Answer

Answer:

A. $H^+ + OH^- \longrightarrow H_2O$

Explanation:

Step1: Write complete ionic equation

$Mg^{2 + }+2OH^ - + 2H^+ + 2NO_3^-\longrightarrow Mg^{2 + }+2NO_3^- + 2H_2O$

Step2: Identify spectator ions

Spectator ions are $Mg^{2 + }$ and $NO_3^-$ as they appear on both sides.

Step3: Write net - ionic equation

Remove spectator ions, getting $H^+ + OH^- \longrightarrow H_2O$
