Answer 2

Given chemical equation is a 'single displacement reaction', in which a non-metal is displaced by a metal. Here, non-metal is hydrogen which is evolved as gas. It is displaced by the metal zinc. Explanation: Generally, a single displacement reaction follows the below pattern: A + BC ----> B + AC In the given equation - Zn(s) + 2Hcl(aq)-----> Zncl2(aq) + H2(g), Zinc (Zn) is a reductant metal that displaces hydrogen (H2) from aqueous solution of Hydrochloric acid (HCl).
