Question

without balancing the final equation, predict the products for the synthesis reaction: mg + br₂ →?

Explanation:

Step1: Determine the charges

Magnesium (\(Mg\)) has a charge of \(+2\) (\(Mg^{2+}\)), and bromine (\(Br\)) in \(Br_2\) has a charge of \(-1\) (\(Br^-\)).

Step2: Use charge - balance for compound formation

To form a neutral compound, the charges must balance. For \(Mg^{2+}\) and \(Br^-\), we need 2 \(Br^-\) ions for each \(Mg^{2+}\) ion.

Answer:

\(MgBr_2\)
