Answer: the resulting compound to be neutral, two bromine anions must combine with one magnesium cation to form magnesium bromide (MgBr2).
Explanation: Because the reaction between the two is
Bromine reacts with magnesium to form magnesium brom and
how is magnesium bromide formed? Magnesium bromide can be synthesized by reacting hydrobromic acid with magnesium oxide and crystallizing the product. It can also be made by reacting magnesium carbonate and hydrobromic acids, and collecting the solid left after evaporation.
