Understanding the Reaction
This reaction is a double displacement reaction, meaning the cations and anions of the reactants switch partners.
* MgCO₃ (Magnesium carbonate) contains Mg²⁺ (magnesium ion) and CO₃²⁻ (carbonate ion).
* NH₄Br (Ammonium bromide) contains NH₄⁺ (ammonium ion) and Br⁻ (bromide ion).
The Products
When these reactants react, they will form:
* MgBr₂ (Magnesium bromide) - formed from the combination of Mg²⁺ and Br⁻.
* (NH₄)₂CO₃ (Ammonium carbonate) - formed from the combination of NH₄⁺ and CO₃²⁻.
The Balanced Equation
The balanced chemical equation for this reaction is:
MgCO₃ (s) + 2 NH₄Br (aq) → MgBr₂ (aq) + (NH₄)₂CO₃ (aq)
Answer
The new magnesium compound formed in the reaction is MgBr₂ (Magnesium bromide).
