Answer 1

Answer:

I believe it results into the formation of Copper Oxide (Cu2O).

Explanation:

Air is composed of approx. 78% Nitrogen and 21% Oxygen. Nitrogen, being approximately inert, refuses to react with the copper rod, henceforth oxygen takes the charge! It reacts with the hot copper rod to form copper oxide.

2Cu + O2 --» 2Cu2O

Metallic copper and water vapour will be formed when hydrogen is passed over heated copper(II) oxide. Hydrogen reduces cupric oxide to free metal in this reaction.
