Answer:
Single displacement.
Step-by-step explanation:
Single replacement:
It is the reaction in which one elements replace the other element in compound.
AB + C → AC + B
Chemical equation:
Fe + Cu(NO₃)₂ → Cu + Fe(NO₃)₃
Balanced chemical equation:
2Fe + 3Cu(NO₃)₂ → 3Cu + 2Fe(NO₃)₃
This is single displacement reaction in which iron displace the copper and form iron nitrate.
Chemical equation:
Cu + Fe(NO₃)₂ → CuNO₃ + Fe
Balanced chemical equation:
2Cu + Fe(NO₃)₂ → 2CuNO₃ + Fe
This is single displacement reaction in which copper displace the iron and form copper nitrate.
