∙ 16y agozinc is larger than copper, thus able to lose electrons easier.
it is also further up the table of reactivity..

∙ 13y agoNo, they are both transition metals though. Look at a periodic table: Zinc-Zn, Copper-Cu.

∙ 10y agoAtomic Mass of Zinc : 65.4g/mol
Atomic mass of Copper : 63.5g/mol
Therefore, Copper is heavier given that they have the same number of moles ( same number of particles).

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 +)
If the two metals copper and zinc are heated then what happens?
when copper and zinc are heated, they create brass :)
Why is zinc and not copper is used for the recovery of silver from cyanide complex?
Zinc is used to precipitate gold from gold cyanide. Zinc will react to form zinc cyanide.
What it the alloy of copper an zinc?

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!
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"
Zinc plus Copper sulphate?
zinc hydrogenate + copper = zinc + copper sulphate
What is mixed with copper to make brass?
Brass is mainly an alloy of copper and zinc. Some alloys do have small amounts of arsenic added also.
Why copper rods not used to separate zinc from zinc sulphate?
Copper rods cannot separate zinc from zinc sulphate because copper is less reactive than zinc, and cannot separate the zinc which is more reactive than copper. If you get copper sulphate and add some zinc to it, you will see solid copper appearing on the bottom of the test tube... The copper cannot push out the zinc from the solution and take its place.
What do copper and zinc make?
SO4 (sulfate) is soluble only when combined with Ba2+, Pb2+, Ca2+, and Sr2+. Since ZnSO4 is not soluble, nothing happens.
