Answer:

It could be whatever you want it to be. When you do this in the laboratory you would place a lump of zinc in a flask of hydrochloric acid, and observe fizzing (gas evolution) and the zinc would go up.

Explanation:

#Zn(s) + 2HCl(aq) rarr ZnCl_2(aq) + H_2(g)uarr#

The (s) and (g) stand for #"solid"# and #"gas"#. The (aq) stands for the #"aquated"# ion. For #Zn^(2+)(aq)#, this is probably #[Zn(OH_2)_6]^(2+)#, a zinc ion surrounded by, AQUATED by, 6 water molecules.
