FeCl3 and H2
iron in hcl
Displacement reaction , as HCl displaces S of FeS to give H2S
The HCl is hydrochloric acid
The reactants are hydrochloric acid (HCl) and sodium hydroxide (NaOH).

HCl and SO2
In the reaction between iron (Fe) and hydrochloric acid (HCl), the Fe reacts with the HCl to form iron chloride (FeCl2) and hydrogen gas (H2). This reaction is a single displacement reaction, where the Fe displaces the hydrogen in the HCl to form the products.
When hydrochloric acid (HCl) reacts with iron powder, the iron oxidizes to form iron(II) chloride (FeCl2) and hydrogen gas (H2) is released. This reaction is a typical metal-acid reaction known as a single displacement reaction. The iron powder will dissolve and you will observe bubbling as the gas is released.
The reactants in the reaction are hydrochloric acid (HCl) and sodium hydroxide (NaOH).
ch3coona+FECL2
I will assume iron II. Fe + 2HCl -> FeCl2 + H2
The answer is FeS + 2 HCl = FeCl2 + H2S. This can be found by noting that at least two molecules of HCl will be needed for each mole of FeS. Trying the simplest possible answer results in a left side of FeS + 2 HCl, which contains one atom each of sulfur and iron and two atoms each of hydrogen and chloride. The stated products, with no multiples, also contains one atom each of iron and sulfur and two atoms each of chlorine and hydrogen. Thus, this equation is balanced.
