a displacement reaction, magnesium displaces hydrogen because it is more reactive
If the HCl is in aqueous solution, the reaction is Mg(s) + 2 HCl(aq)-> MgCl2(aq) + H2(g).
This is a single replacement reaction. It is also an oxidation/reduction reaction
This is a single displacement reaction.
oxidation/reduction
Mg + 2HCl -----> MgCl2 + H2

Salt formation reaction, reducto-oxidative reaction (redox)
The synthesis equation for MgCl2 is Mg + Cl2 -> MgCl2. The decomposition reaction is MgCl2 - heat-> Mg + Cl2.
The decomposition reaction of magnesium dichloride results in magnesium metal and chlorine gas. The reaction is MgCl2 -> Mg + Cl2.
MgCl2 contain 25,537 % magnesium and 74,463 % chlorine. The atomic ratio is 2, the mass ratio is approx. 3.
MgBr2 + Cl2 yields MgCl2 + Br2 is an example of an anionic single replacement chemical reaction.

Is an excellent example of a series of random letters and numbers that somehow manage to fail utterly at being a question.
3 MgCl2 + N2 = Mg3N2 + 3 Cl2
MgCl2 contain 25,537 % magnesium and 74,463 % chlorine. The atomic ratio is 2, the mass ratio is approx. 3.
Cl2 has the lowest boiling point of these four substances.
Redox reaction.
MgCl2 → Mg + Cl2
