Answer 2

Answer: colorless.

Explanation:

Single replacement reaction is a chemical reaction in which more reactive element displaces the less reactive element from its salt solution.

As zinc is more reactive than hydrogen, it displaces hydrogen from its salt solution and forms zinc salt and hydrogen.

The balanced chemical reaction will be:

$Zn+2HCl\rightarrow ZnCl_2+H_2$

Zinc is a bluish-silver metal and on formation of $ZnCl_2$ , it turns colorless.
