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

When zinc oxide and copper are combined, a redox reaction occurs where zinc displaces copper in the reaction. The result is zinc oxide and copper oxide formed as products.

∙ 11y agoYou can't combine zinc oxide and copper because they are both metals! You can combine base and acid. You can't combine metal and metal. It cannot be done. Never heard of it.

Why does zinc plus copper oxide equal copper plus zinc oxide?
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.
How do you separate copper from copper oxide?
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
What decomposes when heated to give zinc oxide?
Zinc carbonate decomposes when heated to give zinc oxide.
What happens when zinc reacts with oxygen?
When zinc reacts with oxygen, it forms zinc oxide. This reaction produces a white powdery substance on the surface of the zinc called zinc oxide.
What do copper and zinc make?
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.

Does zinc usually combine with copper?
Alloys of zinc and copper are well known. There are no chemical compounds of zinc and copper.
What happens to magnesium carbonate copper carbonate zinc carbonate and calcium carbonate when they are heated?
They form magnesium oxide, copper oxide etc. and will form carbon dioxide as a byproduct.
What does Zinc usually combine with?
copper

What does copper oxide plus zinc metal form?
Zn(s) + CuO(s) → ZnO(s) + Cu(s) Copper metal and Zinc Oxide is formed.
What happens to the zinc oxide when zinc is formed?
It is 'freed' from oxygen
What decomposes when heated to give zinc oxide?
Zinc carbonate decomposes when heated to give zinc oxide.
What happens when zinc and oxygen combine?
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 is the yellow powder created when heating zinc oxide?
what happens to calcium oxide and zinc oxide when heated?
What happens when zinc reacts with oxygen?
When zinc reacts with oxygen, it forms zinc oxide. This reaction produces a white powdery substance on the surface of the zinc called zinc oxide.
What compound is formed when zinc and oxygen combine?
Zinc oxide is formed when zinc and oxygen combine. It is a white powder with a variety of industrial uses, including in sunscreen, cosmetics, and as a pigment in rubber and plastics.
