Question

HCl--X--Mg(OH)2--MgSO4

Answer 1

2HCl+Mg⇒MgCl2+H2
MgCl2+2NaOH⇒Mg(OH)2+2NaCl
Mg(OH)2+H2SO4⇒MgSO4+2H2O

Answer 2

The chemical equation you provided seems incomplete as it does not specify the reactants and the products. However, based on the presence of hydrochloric acid (HCl), magnesium hydroxide (Mg(OH)2), and magnesium sulfate (MgSO4), I can suggest a possible chemical reaction that might be occurring.

HCl + Mg(OH)2 → MgCl2 + H2O

This is the balanced chemical equation for the reaction between hydrochloric acid and magnesium hydroxide. The products formed are magnesium chloride (MgCl2) and water (H2O). This reaction is also known as an acid-base neutralization reaction.

If we add magnesium sulfate (MgSO4) to the mixture, no reaction will occur between MgSO4 and HCl since MgSO4 is a salt and is not acidic or basic. Therefore, the final mixture would contain a solution of magnesium chloride (MgCl2) and a solid precipitate of magnesium hydroxide (Mg(OH)2) which is insoluble in water.
