1)Write the BALANCED equation for the reaction
with CORRECT state symbols:
Mg(s) +2HCl(aq)---------->MgCl2(aq) +H2(g)
2)Now rewrite the equation replacing aqueous substances
as they would appear in solution( ie)as ions.Leave
everything else as is in the standard state.
Mg(s) + 2H+ (aq) + 2Cl-(aq)---->Mg2+(aq) +2Cl-(aq) +H2(g)
3)Now cancel ions common to both sides ,that is,spectator
ions.
Cancel the 2Cl-(aq) on each side.
4)Rewrite the equation without what you have canceled.
Mg(s) + 2H+(aq)------>Mg2+(aq) + H2(g).
Good Luck.
The net ionic equation for the reaction would be: Mg(OH)2 + 2HCl -> MgCl2 + 2H2O. This equation represents the formation of magnesium chloride and water from magnesium hydroxide and hydrochloric acid.
The net ionic equation for MgCl2 and AgNO3 is: Mg^2+ (aq) + 2Ag^+ (aq) -> Mg^2+ (aq) + 2AgCl (s), where the spectator ions Cl^- and NO3^- are omitted.
The chemical equation is:Mg+ + 2 OH- = Mg(OH)2(s)
The net ionic equation for the given reaction is H+ (aq) + OH- (aq) → H2O (l)

To balance the equation Zn + HCl → ZnCl2 + H2, you need to ensure that the number of each type of atom is the same on both sides of the equation. To balance it, you would need to write it as Zn + 2HCl → ZnCl2 + H2. This equation balances the number of zinc, hydrogen, and chlorine atoms on both sides.
