fillings? tick the correct answers​

Answer 1

When dilute Hydrochloric acid is added to iron filings, iron chloride & hydrogen gas is produced. The iron displaces hydrogen from hydrochloric acid to form iron (II) chloride & hydrogen gas. ... Thus the answer is option (A) Hydrogen gas and iron chloride are produced.

Hope it helps you

Answer 2

What happen when dilute hydrochloric acid is added to iron filling?

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.
