Question

Quizplus · Accepted Answer

This reaction involves the transfer of electrons from Mg to H+ ions in HBr, resulting in the formation of Mg2+ ions and H2 gas (oxidation of Mg) and Br- ions (reduction of H+ to H-). Therefore, it is an oxidation-reduction (or redox) reaction.

The Reaction: Mg(s)+ 2 HBr(aq) →\rightarrow→ MgBr2(s)+ H2(g)is an Oxidation-Reduction Reaction

The Reaction: Mg(s)+ 2 HBr(aq) $\rightarrow$ MgBr₂(s)+ H₂(g)is an Oxidation-Reduction Reaction
