Identify the oxidation-reduction reactions among the following:
1.Zn(s) + Cu²⁺(aq) → Zn²⁺(aq) + Cu(s)
2.2 Na(s) + Cl₂(aq) → 2NaCl(s)
3.2 Mg(s) + O₂(g) → 2 MgO

Question

Identify the oxidation-reduction reactions among the following: 1.Zn(s)+ Cu²⁺(aq)→ Zn²⁺(aq)+ Cu(s) 2.2 Na(s)+ Cl₂(aq)→ 2NaCl(s) 3.2 Mg(s)+ O₂(g)→ 2 MgO

Quizplus · Accepted Answer

All the reactions involve transfer of electrons from one species to another, indicating they are oxidation-reduction reactions. In reaction 1, Zn is oxidized and Cu2+ is reduced. In reaction 2, Na is oxidized and Cl2 is reduced. In reaction 3, Mg is oxidized and O2 is reduced.
