Question

A mixture of Copper and Zinc was dropped in a flask containing Dil HCL hydrogen gas was a bold immediately this happened because of the reaction of

Answer 1

Answer:

metal with acid

Explanation:

acids react with metals to form hydrogen gas

Answer 2

Zinc with dilute HCl.

Explanation:

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

Metals which are placed higher then hydrogen are more reactive than hydrogen and thus can easily lose electrons as compared to hydrogen.

Zinc can easily lose electrons than hydrogen and get oxidized to $Zn^{2+}$ and $H^+$ from HCl get reduced to give Hydrogen.

$Zn+2HCl\rightarrow ZnCl_2+H_2$

$Cu+2HCl\rightarrow \text {no reaction}$
