The balanced equation would be:
MgBr2 + Cl2 ----> MgCl2 + Br2
Note: The equation is already balanced, both Cl and Br are diatomic elements they cannot exist alone as Cl or Br, they must be Cl2 and Br2. Also, this reaction happens because Cl is more active than Br, so it can displace it (halides activity series).
MgBr2 + Cl2 --> MgCl2 + Br2
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.
Fe + MgCl2 ---> Mg + FexCl2
2Na + Cl2 -> 2NaCl
MgCl2 + H2SO4 ---> MgSO4 + 2HCl
MgBr2 + Cl2 --> MgCl2 + Br2
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.
Fe + MgCl2 ---> Mg + FexCl2
H2 + Cl2 --------> 2HCl
2K + Cl2 ---> 2KCl
2Na + Cl2 -> 2NaCl
A true reaction don't exist between magnesium chloride and sulfuric acid.
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.
This equation is MgBr2 + 2 HCl = MgCl2 + 2 HBr.
MgCl2 + H2SO4 ---> MgSO4 + 2HCl
This equation is Mg + 2 HCl -> MgCl2 + H2.
2K+Cl2------->2KCl
