Explanation:
A solid state is represented by (s) in a chemical reaction equation whereas when a compound is soluble in the solution then it is said to be aqueous solution and it is denoted as (aq) in a chemical reaction equation.
On the other hand, gas is denoted by a symbol (g) in the chemical reaction equation.
Therefore, in the reaction [tex]Zn(s) + 2HCl(aq) \rightarrow H_{2}(g) + ZnCl_{2}(aq)[/tex], zinc chloride ([tex]ZnCl_{2}[/tex]) product is a substance that is dissolved in solution.
