What happens if coke is heated with air with copper oxide?

The coke, C will be in excess and initially combust to make CO. CO + CuO = CO2 + Cu…..this needs heat so the C acts as both fuel and reducing agent. C + 2CuO = CO2 + 2Cu is also viable. read more

Heated copper metal reacts with oxygen to form the black copper oxide. Thecopper oxide can then react with the hydrogen gas to form the copper metal and water. read more

A copper is oxidized to black copper oxide by air when heated . The copper begins to react more rapidly with oxygen from the air and a darker color can be seen on the surface of the copper.its an oxidation Reaction (with oxygen)2 Cu(s ) + O2(g ) -- 2 CuO(s ) read more
