The limiting reagent is sodium hydroxide.

Sodium hydroxide (NaOH) react with dilute Hydrochloric Acid (HCl) to form Sodium chloride (NaCl) and water (H2O).
By starting with a balanced equation. Mg + 2HCl -> MgCl2 + H2 when they say sufficient magnesium they imply that magnesium is in excess and HCl limits and drives the reaction, or that both are equal in molarity/mass 54.75 g HCl (1 mole HCl/36.458 g)(1 mole MgCl2/2 mole HCl)(95.21 g/1 mole MgCl2) = 71.49 grams magnesium chloride produced -----------------------------------------------------------
They wont react with ammonium chloride, they react to form it.
Magnesium chloride: 81,95 g are obtained.
Mg(OH)2 + 2HCl >> MgCl2 + 2H2O

hydrochloric acid and sodium hydroxide
magnesium + chlorine --> magnesium chloride Mg (s) + Cl2 (g) --> MgCl2 (s) 5.60 g Mg x 1 mol Mg x 1 mol MgCl2 x 95.21 g MgCl2 = 21.9 g MgCl2 ..................24.31 g Mg. 1 mol Mg........ 1 mol MgCl2
Let's see.Mg + 2HCl -> MgCl2 + H2Looks like magnesium chloride. And a little hydrogen gas.
First, the sea water is collected in large basins and heated to evaporate some of the water. This yields a concentrated solution of water and various salts which are mixed with calcium hydroxide (lime) to yield a magnesium hydroxide precipitate. The precipitate is then reacted with hydrochloric acid to yield magnesium chloride. This is then separated into molten magnesium metal and chlorine gas ions through the electrolysis process. The chlorine is reacted with hydrogen to yield hydrochloric acid to be recycled, while the molten magnesium is then cast into ingots.
the white ash is the chemial product produced when Mg is reacted with oxide.There the white ash is MgO(magnesuim oxide)

Magnesium generally appears in two valence forms. The pure, non-reacted element, Magnesium, has no charge. Reacted Magnesium has a valence of +2
One such salt would be aluminum chloride since it is soluble but when reacted with ammonium hydroxide, the insoluble aluminum hydroxide forms a precipitate. Not sure what is meant by "is insoluble in excess", however.
This is when acetylene reacted with one of the magnesium bromide. For instance, acteylene reacted with methyl magnesium bromide forming 3-hexa-1-eyne.
