Iron makes a complex with thiocyanate. The rest makes no sense.

One possible reaction that can occur is the formation of a complex ion between Fe₃+ and SCN-, which is Fe(SCN)₂+. This complex ion has a deep red color and is often used as an indicator for the presence of Fe₃+ or SCN- The equation for this reaction is:

FeCl₃ + NH₄SCN -> Fe(SCN)₂+ + NH₄Cl + Cl-

Another possible reaction that can occur is the reduction of Fe₃+ to Fe₂+ by Na₂S₂O₃, which is a common reducing agent. This reaction also produces Na₂SO₄ and H₂SO₄ as byproducts. The equation for this reaction is:

FeCl₃ + Na₂S₂O₃ + H₂O -> FeCl₂ + Na₂SO₄ + H₂SO₄ + Cl-

A third possible reaction that can occur is the displacement of Cu₂+ by Fe₂+, which results in the formation of Cu and Fe(NO₃)₂. This reaction is a redox reaction, where Fe₂+ loses electrons and becomes Fe₃+, while Cu₂+ gains electrons and becomes Cu. The equation for this reaction is:

FeCl₂ + Cu(NO₃)₂ -> Cu + Fe(NO₃)₂ + Cl-

Combining these three reactions, we can write the overall equation for the reaction between FeCl₃, NH₄SCN, Na₂S₂O₃, and Cu(NO₃)₂ as:

FeCl₃ + NH₄SCN + Na₂S₂O₃ + Cu(NO₃)₂ -> Fe(SCN)₂+ + NH₄Cl + Na₂SO₄ + H₂SO₄ + Cu + Fe(NO₃)₂

[ChenBeier]

FeCl₂ + Cu(NO₃)₂ -> Cu + Fe(NO₃)₂ + Cl-

This is nonsense.
You have non balanced equation according charges.
