CuO + Fe –> FeO + Cu; exothermic

That would be my suggestion, but I only have chemistry since that school year, so maybe someone would know more…

It would be welcome if you asked a specific question. This is also a question of courtesy. Otherwise you have to guess what you expect.

Secondly, it would be good to make a proposal for a solution.

Thirdly, to solve mamue1968, I would not let the "+E" go through my teaching. Energy is not a substance which does not belong in this form to the reaction equation.

Fourthly, Fe2O3 and CuO are probably meant, but there are other oxides of these metals.

Copper oxide and iron → Iron oxide and copper CuO + Fe → FeO + Cu (redox reaction) The copper oxide releases the oxygen to the elementary iron. This is an exothermic reaction, since the mixture has continued to anneal after a short heating even without Bunsen burner flame.
