Copper cannot displace zinc from its salt solution?
because in table of re-activity of metals it is below zinc
What are the reactions of copper and zinc metal using concentrated nitric acid concentrated sulfuric acid potassium chloride solution and zinc powder metal?
copper+nitric acid > copper nitrate+hydrogen copper+sulpuric acid> copper sulphate+ hydrogen copper+potassium chloride> copper chloride+ hydrogen copper+ zinc carbonate (powder metal) > copper+ zinc + water + carbon dioxide zinc+nitric acid > zinc nitrate+ hydrogen etc just replace the copper in the above equations with 'zinc' for all the zinc solutions x
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"
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.
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!
What would happen if you zinc into hydrohloric acid?
you would get Zinc Chloride, a salt. This is because when you add a metal to an acid, you get a salt (plus some water, which just dilutes the acid)
Could copper also cause zinc ions to precipitate?
No. Ions do not precipitate on their own. Since zinc is more reactive that copper it will replace copper. So placing zinc in a solution of a copper salt will cause elemental copper to precipitate.
What will happen when copper is put in zinc nitrate solution?
Nothing. Zinc is more reactive than copper, and zinc has already undergone oxidation to become an ion (remember, zinc nitrate is soluble.) So the copper will just sit there because it's not reactive enough to do anything.

What and when did we use zinc in science?
Zinc is used in very simple batteries (usualy for demonstration rather than actual power scources.) generaly in chemistry, you make a galvanic cell out of zinc rod, zinc sulphate, copper wire, copper rod, copper sulphate and a salt bridge made of potassium nitrate, and that will give you a small direct current of electrons from the zinc side of the cell to the copper side of the cell and a conventional current from copper to 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.
What coin will rust faster in salt water?
A penny will rust faster because it made entirely of zinc with a thin outer coating of copper, and zinc is made to rust unlike nickel which is used to make nickels, dimes, etc...
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.
Alloyed with copper to make brass?
Zinc
