Question

Why Fe +HCl = FeCl2+H2
From where the cl2 (2)came

Answer 1

Answer:

Let us consider the reaction between acid and metal

Acid + Metal → Salt + Hydrogen gas (H2)

in this case

Acid = Dilute HCl

Metal = Iron (Fe)

∴ HCl + Fe → FeCl2 + H2

Let us balance the equation,

2HCl + Fe → FeCl2 + H2

when dilute HCl is added to Fe then Ferrous chloride ( FeCl2) and hydrogen gas (H2) will be formed.
