When a strip of copper is placed in aqueous silver nitrate, a displacement reaction takes place. What is the ionic equation for the reaction which takes place?

AAg⁺(aq) + Cu(s) → Ag(s) + Cu²⁺(aq) + e⁻

B2Ag⁺(aq) + Cu(s) → 2Ag(s) + Cu²⁺(aq)

C2AgNO3(aq) + Cu(s) → 2Ag(s) + Cu(NO3)2(aq)

D2Ag(s) + Cu²⁺(aq) → 2Ag⁺(aq) + Cu(s)

✓ Correct answer

B: 2Ag⁺(aq) + Cu(s) → 2Ag(s) + Cu²⁺(aq)
