Cu is much less reactive than Fe, because it is possible to find natural Cu nuggets and it is not possible to find natural Fe nuggets. The only natural form of metallic Fe that occurs is in NiFe alloy meteors, which formed in space not on earth and the surface of these meteors rusts rapidly after landing.
It is because zinc is more reactive than copper and hence replaces copper from its solution.For your convenience, here is the reactive series of elements in order of decreasing reactivity:-Potassiumsodiumbariumcalciummagnesiumaluminiummanganesezincironnickeltinleadhydrogencoppermercurysilvergoldplatinum
Give balanced equation when copper reacts with silver nitrate.Add: 2AgNO3 + Cu ---> Cu(NO3)2 + 2AgThis is a single replacement reaction in which copper replaces the silver in the silver nitrate, resulting in the formation of elemental silver, which will precipitate out of solution.
The element copper makes the blue-green fireworks.
The acid that reacts with copper(II) carbonate to give a blue solution is hydrochloric acid (HCl). This reaction forms a solution of copper(II) chloride, which appears blue due to the presence of copper ions.
Sodium does not tarnish in the same way that metals like silver or copper do. However, sodium is highly reactive and easily reacts with moisture or other substances in the air, forming sodium oxide or sodium hydroxide on its surface. This can give the appearance of tarnish, but it is actually a chemical reaction rather than oxidation of the metal itself.

If you look at reactivity series, you will find zinc to be more reactive than hydrogen while copper being less reactive than it. Therefore zinc is able to displace hydrogen from sulphuric acid while copper is not. The reaction with zinc is:- Zn + H2SO4 -------> ZnSO4 +H2 The reaction with copper is Cu + H2SO4 ---------> No reaction
Adding zinc to copper sulfate will result in a displacement reaction that will create copper metal to precipitate as a solid. CuSO4(aq) + Zn(s) ---> ZnSO4 + Cu(s) This reaction is quite exothermic too, meaning it will give off alot of heat - enough to make it too hot to hold the reaction beaker in bare hands.
because it isn't a reactive metal
To give a higher surface area for the reaction
copper and chlorine This would require a chemical reaction.

The element copper makes the blue-green fireworks.
The reaction between copper, water, and oxygen to form copper hydroxide is a chemical reaction that involves oxidation. Copper reacts with oxygen in the air to form copper oxide, which then reacts with water to give copper hydroxide. This reaction can be classified as both oxidation and hydrolysis.
A displacement reaction occurs when a more reactive element displaces a less reactive element from its compound. An example is the reaction between zinc metal and hydrochloric acid to form zinc chloride and hydrogen gas. In this reaction, zinc displaces hydrogen from hydrochloric acid to form zinc chloride and hydrogen gas is evolved.
The lack of reaction between copper metal and acid is a chemical property because it indicates the chemical stability of copper in acidic environments. This property is due to the formation of a protective layer of copper oxide on the metal surface.
When vinegar reacts with copper, it forms copper acetate, which can give the copper surface a greenish-blue color known as patina. This patina changes the appearance of the copper surface by creating a tarnished or aged look.
