zinc is more electropositive and therefore is highly reactive metal.hence it can not be easily displaced from its solution of ZnSO4.on the other hand,copper is less electropositive and can be readily displaced from its solution more active metal such as zinc.

What it the alloy of copper an zinc?
Alloys that contain only copper and zinc are usually called "brass"; there are also some alloys that contain one or more other metals in addition to copper and zinc, and these usually have another name.
Alloyed with copper to make brass?
Zinc
Why is zinc negative amd copper positive?
Zinc is more electronegative than copper. As a result, zinc acts as the anion(anode), while copper loses electrons and becomes positive (cathode). Electrons flow from the zinc to the copper ( - to +)
How is copper extracted from earth?
copper is extrcted in diffrent country
If the two metals copper and zinc are heated then what happens?
when copper and zinc are heated, they create brass :)
Name four important transition elements which are extracted from south African mines?
iron, mecury, zinc, copper
Is hydrometallurgy used in mining copper?
Hydrometallurgy is used for the processing of copper.Example: Leaching of copper oxide ores using a solution containing sulphuric acid. The Copper can then be recovered from solution using solvent extraction and electrowinning.
What is meant by - smelting?
Smelting is the process which ore goes through so that a metal can be extracted from it. It involves heating the rock to very high temperatures. Copper, for instance, can be extracted at temperatures of about 1200 °C.Actually, smelting is a process when a metal which is more reactive than copper needs to be extracted. For example, zinc is more reactive than copper so it has to be extracted smelting. It can be extracted by heating its ore with charcoal aka smelting.--different person

Does zinc usually combine with copper?
Alloys of zinc and copper are well known. There are no chemical compounds of zinc and copper.
Does copper displace zinc from zinc sulphate?
No, zinc will displace copper from copper sulphate but not the other way around.
What two things happen when zinc is added to copper sulphate?
The Zinc will displace the copper. It will become Zinc Sulphate. The word equation will be Zinc + Copper Sulphate -----> Copper + Zinc Sulphate. Hope this helps!
Is zinc extracted or processed?
extracted, it is a mineral that occurs naturally in the earth.
Alloyed with copper to make brass?
Zinc
Is the zinc and copper are solids?
Zinc and copper are solid metals.
What are copper and zinc molecules?
Copper and zinc are atoms, not molecules.
Why does zinc plus copper oxide equal copper plus zinc oxide?
Because the zinc is "oxydised" and the copper is "reduced"
