Zinc is more reactive than Hydrogen, and so it will replace it and bond with the Cl atoms. This is a standard single displacement reaction:
Zn + 2HCl --> ZnCl2 + H2
Copper is less reactive than Hydrogen, so it will not form a compound with the Cl atoms. The reactivities of various elements can be found on any RedOx table. A metal with a low value has a strong potential to be oxidized (i.e. give up electrons and form a compound with a negative ion)
Copper is less reactive than hydrogen (look at the reactivity series), so will not take the place of hydrogen in an acid to form a salt and hydrogen.
Metals which are more reactive than hydrogen will take the place of hydrogen to form a salt + hydrogen gas.
For example: Magnesium + hydrochloric acid --> magnesium chloride + hydrogen
Because copper is lower in the electromotive series than hydrogen, or more fundamentally, because the magnitude of the change in Gibbs free energy when a single atom of elemental hydrogen ionizes is greater than the magnitude of the change in Gibbs free energy when a single atom of elemental copper ionizes. Therefore, elemental copper does not have sufficient chemical potential to liberate elemental hydrogen from compounds in which hydrogen has an oxidation state of +1.
because copper doesnt want to react with hydrochloric acid.he is to busy reacting with nitric acid.

Sorry, copper does not react with hydrochloric acid as it is not reactive enough to do so. Only metals above hydrogen in the reactivity series will react with dilute acids.
Copper does not react with dilute HCl, but dissolves in hot concentrated HCl, and dissolves quickly if oxygen is bubbled through.
because copper is a less reactive metal
Gold , Silver and copper. Copper can be made to react witg 16M nitric acid. Gold can be made to reract with 'Aqua-regia' a mixture of nitric acid and hydrochloric acid .
when niric acid is added to copper the compound formed will be copper nitrite,gold does not change because nitric acid will not react with gold,but it react with any other materials.thish is the reason why gold does not change sathish s sathya
The reaction of copper pennies (pre 1983) is a very intense exothermic reaction. The copper is oxidized by the acid.
Displacement reaction React Copper Nitrate with a more reactive metal such as Sodium or Calcium and you will get Sodium or Calcium Nitrate + Copper and Hydrogen x
Cu + 2HNO3 -> Cu(NO3)2 + H2 Ideally, yes. How dilute? In school experiments the nitric acid would be dilute.
No

Plutonium easily react with nitric acid.
1.388 g HNO3
Aluminium is passive towards Nitric acid because Nitric acid forms a protective thin film on surface of Aluminium which protects from further reaction.
No, it does not
Nitric acid (HNO3) and copper(II) sulfate (CuSO4) will react in a double replacement reaction to produce copper(II) nitrate and sulfuric acid. The correctly balanced equation is: 2HNO3 + CuSO4 --> Cu(NO3)2 + H2SO4
Platinum doesn't react with nitric acid.
