In a chemical equation ,we must finish our chemical reaction with as many atoms of each element as when we started.the balanced chemical equation for the reaction of solid magnesium metal and barium chloride is given as .Mg + Bacl 2 -> Mgcl2 + Ba.
Fe + MgCl2 ---> Mg + FexCl2
A balanced equation MUST have EQUAL numbers of EACH type of atom on BOTH sides of the arrow.The balanced equation for the reaction magnesium chloride plus sulfuric acid is;MgCl2 + H2SO4 ------> MgSO4 + 2HCl.
This equation is Mg + 2 HCl -> MgCl2 + H2.
The concentration of the acid is irrelevant. Magnesium chloride and hydrogen gas are formed.
The synthesis equation for MgCl2 is Mg + Cl2 -> MgCl2. The decomposition reaction is MgCl2 - heat-> Mg + Cl2.

When magnesium reacts with copper chloride, an exchange reaction occurs in which magnesium replaces copper, resulting in the formation of magnesium chloride and copper. The balanced chemical equation for this reaction is: Mg + CuCl2 → MgCl2 + Cu.
The concentration of the acid is irrelevant. Magnesium chloride and hydrogen gas are formed.
The synthesis equation for MgCl2 is Mg + Cl2 -> MgCl2. The decomposition reaction is MgCl2 - heat-> Mg + Cl2.
Mg(OH)2 + 2HCl >> MgCl2 + 2H2O
MgCl2(soln) + 2NaF(soln) ------> MgF2(s) + 2NaCl(aq)
This is not 'the balanced equation' of MgSO, what is meant is the chemical FORMULA of magnesium sulfate or magnesium sulfite.These are: MgSO4 and MgSO3respectively.
CuCl
The balanced chemical equation is: MgO + H2O → Mg(OH)2 The product formed in this reaction is magnesium hydroxide.
There is NO reaction at all.
