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.
The balanced chemical equation for this reaction is: FeS + 2H⁺ → Fe²⁺ + H₂S
This is a double displacement reaction. Iron(II) sulfide (FeS) and hydrochloric acid (HCl) react to form iron(II) chloride (FeCl2) and hydrogen sulfide gas (H2S).
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.
FeS is not a chemical equation but a chemical formula; FeS is the chemical formula of iron sulfide.
This reaction is a double displacement reaction, also known as a metathesis reaction. Iron(II) sulfide reacts with hydrochloric acid to form iron(II) chloride and hydrogen sulfide gas.
The balanced equation for the reaction between iron(II) sulfide (FeS), hydrochloric acid (HCl), and hydrogen sulfide (H2S) is: FeS + 2HCl + H2S --> FeCl2 + H2S
Single Displacement
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
Yes, the products are hydrogen sulfide and iron II bromide. 2HBr + FeS --> FeBr2 + H2S
This is a double displacement reaction. Iron(II) sulfide (FeS) and hydrochloric acid (HCl) react to form iron(II) chloride (FeCl2) and hydrogen sulfide gas (H2S).
When iron(II) sulfide (FeS) reacts with hydrochloric acid (HCl), the following chemical reaction occurs: FeS + 2HCl → FeCl2 + H2S. This reaction forms iron(II) chloride (FeCl2) and hydrogen sulfide (H2S) gas.
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.
To detect hydrogen sulfide production, a heavy metal salt containing ferrous iron is added to a nutrient culture medium, when hydrogen sulfide is produced the sulfide reacts with the metal salt producing the black precipitate.
As in festival, no the prefix fes does not mean anything. If your talking up the suffix fess, as in confess, it means to speak.
In the reaction FeS + 2HCl --> FeCl2+ H2S, the iron replaces the hydrogen and the hydrogen replaces the iron. This is two replacements, so the reaction is a double replacement reaction. (It's sometimes also called a double displacement reaction.)
FeS + 2HCl >> FeCl2 + H2S 75 grams FeS (1mole FeS/87.92 grams)(2 mole HCl/1 mole FeS) = 1.71 moles HCl 2 Molar HCl = 1.71 moles HCl/Liters = 0.855 Liters HCl, or as asked for; 855 milliliters of hydrochloric acid needed
