You have the wrong formula for magnesium hydroxide. It should be Mg(OH)2.
To determine if a ppt will form or not, calculate Qsp and compare that with Ksp for Mg(OH)2.
Predict whether or not a precipitate will form upon mixing 75.0 mL of a NaOH solution with pOH = 2.58 with 125.0 mL of a 0.018 M MgCl2 solution. Identify the precipitate, if any.
Express as a chemical rxn
NaOH(aq) + MgCl2(aq) => NaCl(s) + MgOH(aq)
I have to balacnce it and identiy the precipitate I think its NaCl. Can you tell me what I am doing wrong with balancing?

will it be
2NaOH(aq)+MgCl2(aq)-> 2NaCl(aq)+ Mg(OH)2(s)
2NaOH(aq)+MgCl2(aq)-> 2NaCl(aq)+ Mg(OH)2(s)
