Reaction of Zinc with Copper(I) oxide (cuprous oxide, Cu2O), a red powder;
2 Zn + Cu2O →2 Zn O + 2 Cu
and Reaction of Zinc with Copper(II) oxide (cupric oxide, CuO), a black powder;
Zn + CuO →Zn O + Cu
Reason :- The most reactive metals (for example Zn) can displace any of the metals (for example Cu) which are lower in the reactivity series; the higher metal reduce the ions of the lower metal. Reference : http://en.wikipedia.org/wiki/Reactivity_series
This is a chemical reaction known as a displacement reaction. Zinc has a higher reactivity than copper, so when zinc is added to copper oxide, it displaces copper from the compound forming zinc oxide and copper metal. This reaction occurs because metals higher in the reactivity series can displace metals lower in the series from their compounds.
I think you mean how do you extract copper from copper oxide, if so here's your answer. Take your copper oxide and heat it with something that is more reactive than copper. Carbon is a good example. The more reactive carbon will oxidise, taking the oxygen from the copper oxide leaving copper. copper oxide + carbon --> copper + carbon dioxide 2Cu0 + C --> 2Cu + CO2
Zinc carbonate decomposes when heated to give zinc oxide.
2 Zn + O2 = 2 ZnO (zinc oxide, a white powder)
Copper and zinc combined form an alloy known as brass. Brass is a durable and malleable material commonly used in various applications, such as in plumbing fixtures, musical instruments, and decorative items.
When copper oxide (CuO) reacts with zinc (Zn), a reduction reaction occurs where zinc reduces copper oxide to produce copper metal and zinc oxide (ZnO). The reaction can be represented by the equation: CuO + Zn → Cu + ZnO. This process involves the transfer of electrons, with zinc acting as the reducing agent. The result is the formation of elemental copper and a zinc oxide byproduct.

Alloys of zinc and copper are well known. There are no chemical compounds of zinc and copper.
They form magnesium oxide, copper oxide etc. and will form carbon dioxide as a byproduct.

Zn(s) + CuO(s) → ZnO(s) + Cu(s) Copper metal and Zinc Oxide is formed.
It is 'freed' from oxygen
Zinc carbonate decomposes when heated to give zinc oxide.
When zinc and oxygen combine, they form zinc oxide. This reaction is typically slow in ambient conditions, but it can be sped up by heating. Zinc oxide is a white powder that is commonly used in sunscreens, ointments, and paints.
what happens to calcium oxide and zinc oxide when heated?
