Final answer:
The reaction of FeS(s) + HCL(aq) > FeCl₂(s) + H₂S(g) when translate into words is A. Iron sulfide reacts with hydrochloric acid to produce ferrous chloride and hydrogen sulfide.
Step-by-step explanation:
The given chemical equation shows the reaction between solid iron sulfide (FeS) and hydrochloric acid (HCl) to produce solid ferrous chloride (FeCl₂) and gaseous hydrogen sulfide (H₂S).
This reaction is a double displacement reaction, also known as a precipitation reaction, where the positively charged iron ions in iron sulfide switch places with the positively charged hydrogen ions in hydrochloric acid, resulting in the formation of ferrous chloride and hydrogen sulfide. Therefore the correct answer is A. Iron sulfide reacts with hydrochloric acid to produce ferrous chloride and hydrogen sulfide.
