the anwer is false
Since it is an ionic compound, the overall charge should be zero. Iron (Fe) has possible different charges which are +2, and +3 however sulfide always has a charge of -2. Therefore, FeS is already balanced. When you write it, instead of writing "Iron Sulfide", you would write "Iron (II) Sulfide" this is because Iron has different charges and you must specify when you write it down.
The balanced chemical equation for the reaction is: ZnS + 2HCl → ZnCl2 + H2S
Single Displacement
The balanced chemical equation for the reaction between H2S (hydrogen sulfide) and CuSO4 (copper(II) sulfate) is: H2S + CuSO4 → CuS + H2SO4 This equation is balanced as it shows the conservation of atoms of each element on both sides of the reaction.
The double replacement reaction between FeCl2 and H2S would result in the formation of FeS (iron sulfide) and 2HCl (hydrochloric acid). Iron chloride (FeCl2) reacts with hydrogen sulfide (H2S) to produce iron sulfide (FeS) and hydrochloric acid (HCl) as products.
The balanced chemical equation for this reaction is: FeS + 2H⁺ → Fe²⁺ + H₂S
CuCl2 + H2S --> CuS + 2HCl Yes, this is the balanced equation here.
iron(II) sulfide + sulfuric acid --> hydrogen sulfide + iron(II) sulfate FeS + H2SO4 --> H2S + FeSO4

Assuming this is the reaction: FeS + H2 --> H2S + Fe, the molar mass of H2S is 34g/mol, so you have about 4.4mol of it. Because the equation features reagents in a 1:1 ratio, this means you will require 4.4mol of FeS. FeS has a molar mass of 88g/mol, and 88x4.4=387.2g FeS required.
The balanced chemical equation for the reaction between oxygen (O2) and hydrogen sulfide (H2S) is: 2H2S + 3O2 -> 2SO2 + 2H2O From the equation, it is a 3:2 ratio of O2 to H2S. Therefore, if 2.3 moles of H2S are present, (2.3 moles H2S) * (3 moles O2 / 2 moles H2S) = 3.45 moles of O2 are needed.
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.
It appears to be a chemical equation where FeS (Iron(II) sulfide) reacts with HCl (Hydrochloric acid) to produce FeCl2 (Iron(II) chloride) and H2S (Hydrogen sulfide gas). It represents a chemical reaction where a solid reactant with an acid forms a different compound and a gas as products.
