Answer:

Mg(NO3)2(aq) + 2NaOH(aq) —> Mg(OH)2 (s) + 2NaNO3 (aq)

Explanation:

Equation for the reaction is given below:

Mg(NO3)2(aq) + NaOH(aq) —>

In solution, Mg(NO3)2 and NaOH will dissociate as follow:

Mg(NO3)2 —> Mg^2+ + 2NO3^-

NaOH —> Na+ + OH-

During the reaction, double displacement occurs as shown below:

Mg^2+ + 2NO3^- + Na+ + OH- —> Mg^2+OH- + Na+2NO3^-

The balanced elemental equation is given as:

Mg(NO3)2(aq) + 2NaOH(aq) —> Mg(OH)2 (s) + 2NaNO3 (aq)
