➡

When dilute hydrochloric acid is added to a metal then Hydrogen gas is produced. When a reactive metal reacts with hydrochloric acid hydrogen gas is produced A reactive metal displaces the hydrogen from acid and release hydrogen gas.

➡ Fe +H₂So₄=FeSo₄+H₂

WHEN IRON AND DILUTE SULPHURIC ACID REACTS WITH EACH OTHER .HYDROGEN GETS DISPLACED AND IRON SULPHATE IS FORMED. THIS IS CALLED DISPLACEMENT REACTION.METAL+ACID=SALT+HYDROGEN

Answer 2

When dilute Hydrochloric acid reacts with a metal Hydrogen gas is produced.
