The reaction is:
Zn(s) + 2HCl(aq) --> ZnCl2(aq) + H2(g).
The word residues is not correct; zinc chloride and hydrogen are called products.
To some degree yes. Most acids, even strong ones such as hydrochloric acid usually have no immediate effect on copper. However if copper is left to sit in concentrated hydrochloric acid for several days it will oxidize. Copper will react vigorously with nitric acid.
Residue left on your plate after eating may be called crumbs or scraps by others.
what is left on filter paper when using filtration? it is residue
Pure water has no residue; residues originate from impurities in water.
There was a powdery residue left over after I evaporated the solution.
if you do the test you have water and salt left over...
When the hydrochloric acid is dropped on limestone it will start to bubble (which is carbon dioxide). After thirty minutes, there will be CaCl2 and water left on the limestone.
A salt and water. For example if you add hydrochloric acid to sodium hydroxide (a base), you will get sodium chloride (a salt) and water. ie. HCl + NaOH -> NaCl + H2O But unless the acid and base are perfectly balanced you'll have some acid or base left over.
A residue is something left over. Fires usually leave a residue of ash.
You get a very violent reaction (so don't do this), and you're left with lithium fluoride and water.
To some degree yes. Most acids, even strong ones such as hydrochloric acid usually have no immediate effect on copper. However if copper is left to sit in concentrated hydrochloric acid for several days it will oxidize. Copper will react vigorously with nitric acid.

Fatty acid oxidation is the process in which fatty acids are broken down by tissues to produce energy. Fatty acids are the residue left from fats being broken down.
The solid material left in evaporating dish is called as Residue.
perhaps no more HCL left or HCl solution is weak PH so the reaction take long time
The adhesive tape left a sticky residue on the glass.
The oily residue was sent to the lab for examination.Go and wash that residue off your hands.
