They form magnesium oxide, copper oxide etc. and will form carbon dioxide as a byproduct.
what happens to calcium oxide and zinc oxide when heated?
Well, isn't that a happy little question! Zinc sulfate is produced by reacting zinc oxide with sulfuric acid. Just like mixing colors on your palette, combining these two substances creates a new compound that can be used for various purposes. Remember, there are no mistakes, just happy little accidents in chemistry!
Zinc chloride is typically made by reacting zinc with hydrogen chloride gas. It can also be produced by dissolving zinc oxide or zinc metal in hydrochloric acid.
When metal reacts with oxygen, it forms metal oxide as the product.
The two do not react. Zinc is more active than copper and thus copper can not displace zinc.
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.

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.

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
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.
Zinc sulfate is typically produced by reacting zinc oxide with sulfuric acid. The chemical equation for this reaction is: ZnO + H2SO4 -> ZnSO4 + H2O.
Zn(s)+H2O(g)-->ZnO(s)+H2(g) easy :)
