Write the net ionic equation for the reaction of sodium chloride with magnesium hydroxide. include the complete ionic equation and label spectator ions. also be sure to label the reactants and products as solid, liquid, gas, or aqueous solutions.

This a long process...
first you write down the equation,in this case:
2NaCl (aq) + Mg(OH)2 (s) ———> MgCl2 (aq) + 2NaOH (aq) .
next you break them up into ions :
(only break up the aqueous solutions)
(2Na+) + (2Cl-) + Mg(OH)2 {leave it together} ———> (Mg2+) + (2Cl-) + (2Na+) + (2OH-).
then look at both sides of equation and cancel the ions that appear twice .
In this case: Cl and Na.
now the remaining is your final net atomic equation:
Mg(OH)2———-> Mg2 + 2OH.
