The zinc in the core of the penny will react in a single replacement reaction with the hcl while the copper will not theoretically react and will be left behind. So if you soak a penny, with cuts in it for the hcl to reach the zinc, will leave behind a copper shell.
-may not be 100%correct as i am not an expert just taking high school chem.

∙ 12y agoThe small amount of copper on the outside of the penny does not allow the hydrochloric acid to reach the zinc. If the copper is scratched away, the exposed zinc will react.

Final product is zinc chloride and hydrogen gas

What is the name of reaction when the zinc react with hydrochloric acid?
It is a single displacement reaction.
What happens when hydrochloric acid is added to zinc powder?
There is a vigorous and exothermic reaction. The hydrochloric acid and zinc react to produce zinc chloride and hydrogen gas. Large amounts of heat are also released.
Does zinc destroy hydrocloric acid?
Matter can neither be created nor destroyed. However zinc does react with hydrochloric acid, producing zinc chloride and hydrogen gas. The hydrochloric acid isn't destroyed, only changed into something else.
Is there a temperature change when zinc granules react with hydrochloric acid?
yes it heats up

molecules of what?
