FeS + HCl yields FeCl2 + H2S
Balanced Equation & Type of Reaction
To balance the equation FeS + HCl -> FeCl2 + H2S, we need to make sure that the number of atoms of each element is the same on both sides of the equation.
The balanced equation is as follows:
FeS + 2HCl -> FeCl2 + H2S
Now, let's identify the type of reaction involved.
The reaction FeS + 2HCl -> FeCl2 + H2S is a double displacement reaction, also known as a precipitation reaction. In this reaction, the cations (Fe2+ and H+) swap partners with the anions (S2- and Cl-) to form new compounds. The product H2S is a gas that bubbles out of the solution, and FeCl2 is a solid that precipitates.
In summary, the balanced equation is FeS + 2HCl -> FeCl2 + H2S, and the type of reaction is a double displacement (precipitation) reaction.
