MgCl2 contain 25,537 % magnesium and 74,463 % chlorine. The atomic ratio is 2, the mass ratio is approx. 3.
NaCl has ther highest melting point, as it is a solid at room temeprature. The other are gases and there fore have much lower boiling points and lower again for melting points.
MgBr2 + Cl2 yields MgCl2 + Br2 is an example of an anionic single replacement chemical reaction.
The synthesis equation for MgCl2 is Mg + Cl2 -> MgCl2. The decomposition reaction is MgCl2 - heat-> Mg + Cl2.

NaCl is an ionic solid with a high boiling point. Cl2 is held together by weak dispersion forces and is a gas at room temperature. That means Cl2 has already boiled and formed a gas at a temperature lower than room temperature.
MgCl2 contain 25,537 % magnesium and 74,463 % chlorine. The atomic ratio is 2, the mass ratio is approx. 3.
MgCl2 → Mg + Cl2
Bromine is diatomic, so 2 atoms make up Bromine as a reactant. Mg + Br2 ----> MgBr2
They yield magnesium chloride. Mg + Cl2 --> MgCl2
