When a blue copper nitrate solution CuNO3 is mixed with a colorless sodium solution Na2S a black precipitate is formed?

Yes, unless the solutions are very dilute. Nickel sulfide is only very slightly soluble and therefore usually precipitates.

when a blue thing is added with a colourless thing, it forms a blue thing.
blue+nothing=blue.

Ni(OH)2+K2SO4 = NiSO4(H2O)6+KOH

NAME OF A metal that replaces silver from silver nitrate solution?
copper will replace silver in silver nitratesolution will precipitate silver and oxidize copper turning to copper nitrate
Why would sliver nitrate precipitate when in contact with copper?
Silver nitrate does not precipitate in this case; elemental silver does. In this reaction, silver nitrate reacts with copper to form elemental silver and copper II nitrate. The silver, which is a metal, is insoluble in water.
What is the net ionic equation for copper 2 nitrate and barium chloride?
Copper nitrate and barium chloride do not react. Barium chloride solution produces a white precipitate with solutions containing sulfate ions.
What is the reaction between copper sulfate and barium nitrate?
the reaction is a precipitate reaction. A precipitate usually makes a solution cloudy. A while later the precipitate drops to the bottom as a solid. It is generally a fine, powdery sediment.
Can you stir silver nitrate solution with a copper spoon why or why not?
No, we cannot stir silver nitrate solution with a copper spoon because , copper is more reactive than silver. Thus,it would displace silver from the silver nitrate solution forming copper nitrate....
Why does copper II nitrate and sodium hydroxide make a precipitate?
when they react, it forms copper hydroxide which is insoluble, and hence a precipitate in the resultant solution of sodium nitrate
NAME OF A metal that replaces silver from silver nitrate solution?
copper will replace silver in silver nitratesolution will precipitate silver and oxidize copper turning to copper nitrate
Is silver more reactive than copper?
Suspend a copper wire in a solution of silver nitrate. Over the course of a few hours the silver nitrate will convert to copper II nitrate, turning the solution blue. Elemental silver will precipitate.

What is the observation of copper (s) plus silver nitrate?
Cu(s) + 2AgNO3(aq) --> 2Ag(s) + Cu(NO3)2(aq)According to the metal activity series, copper is more reactive than silver, so the copper will replace the silver in the silver nitrate compound.https://en.wikipedia.org/wiki/Reactivity_seriesThe silver metal will precipitate out of solution, forming along the piece of copper, which goes into solution, combining with the aqueous nitrate ion. If this reaction goes to completion, all of the copper will go into solution as copper(II) nitrate, and all of the silver metal will precipitate out of solution.

Copper wire is put in a solution of silver nitrate. Crystals of silver form. Why does the solution go blue and how do you show that it's a redox reaction?
because a silver precipitate is formed.

How to Extract copper out of copper nitrate?
by electrolysis(molten or aqueous they are the same in results)
What results from copper II nitrate reacting with sodium hydroxide?
Solutions of copper (II) compounds will undergo precipitation reactions with sodium hydroxide solution when mixed together to produce a bright blue precipitate of copper (II) hydroxide and a solution of a sodium salt.The chemical equations for the reaction between Copper (II) nitrate and Sodium hydroxide are as follows:Cu(NO3)2 (aq) + 2NaOH (aq) → Cu(OH)2 (s) + 2NaNO3 (aq)Copper II nitrate + sodium hydroxide → copper II hydroxide + sodium nitrate
What happens when you heat copper hydroxide and sodium nitrate?
When heat copper hydroxide and sodium Nitrate the pale blue precipitate change into black solid
