(b) Chlorine gas and iron hydroxide are produced.
(c) No reaction takes place.
(d) Iron salt and water are produced
Answer
(a) Hydrogen gas and iron chloride are produced.
Explanation
The chemical reaction between HCl and Fe (Iron fillings) can be written as follows
2HCl + Fe → FeCl 2 + H 2
Fe displaces H from HCl to form FeCl 2
(Fe being more reactive than H, displaces it from it’s from its compound)
