Correct option is C
The correct answer is (c) Hydrogen.
· When a piece of zinc metal is placed in hydrochloric acid, hydrogen gas is evolved. The reaction between zinc and hydrochloric acid produces zinc chloride and hydrogen gas.
Chemical Reaction:
Zn+2HCl→ZnCl2+H2↑
Information Booster:
· Carbon Dioxide : Produced when acids react with carbonates or bicarbonates.
· Nitrogen and Oxygen : Not typically evolved in this type of reaction.
