Understanding the Reaction
Magnesium (Mg) is a metal and bromine (Br₂) is a nonmetal. They react to form magnesium bromide (MgBr₂), an ionic compound. The balanced chemical equation for this reaction is:
Mg + Br₂ → MgBr₂
Interpreting the Equation
* The coefficients in the balanced equation represent the ratio of moles of reactants and products.
* The coefficient for magnesium is 1, and the coefficient for bromine is 1.
Answer
This means that one magnesium atom is needed to react with one bromine molecule (Br₂) to produce one molecule of magnesium bromide.
