Chemistry Predicting Precipitates Questions

Q#1 Predict whether a precipitate of PbF2 (Ksp = 3.3×10^-8) will form if 100 mL of 0.10 mol/L Pb(NO3)2 is added to 100 mL of 0.03 mol/L of NaF.

Q#2Predict whether a precipitate of Mg(OH)2 (Ksp = 5.6×10^-12) will form if 50 mL of 0.20 mol/L MgCl2 is added to 50 mL of 0.0025 mol/L of NaOH.
