A : Sodium Chloride ⟶ Hydrogen Chloride

B : Hydrogen Chloride ⟶ Iron (II) chloride

C : Hydrogen Chloride ⟶ Ammonium chloride

D : Hydrogen Chloride ⟶ Lead chloride.

A: $\text{NaCl} + \text{H}$2\text{SO}4 \xrightarrow{\lt 200 \degree\text{C}} \text{NaHSO}_4 + \text{HCl [g]}

B: Fe + 2HCl (dil.) ⟶ FeCl₂ + H₂ [g]

C: NH₄OH + HCl (dil.)⟶ NH₄Cl + H₂O

D: $\text{PbO}$2 + 4\text{HCl} \xrightarrow{\Delta} \text{PbCl}2 + 2\text{H}2\text{O} + \text{Cl}2
