Question

Write symbolic representation for the following word equation and balance them:

(h) Iron sulphide + Hydrochloric acid(dil) $\to$ Iron(Il) chloride + Hydrogen sulphide

Answer 1

Symbolic representation:
$\text{FeS}+\text{HCl}\to {\text{FeCl}}_2+{\text{H}}_2\text{S}$

• To equalize $\text{H}$ and Cl, multiply $\text{HCl}$ by 2 .$\text{FeS}+2\text{HCl}\to {\text{FeCl}}_2+{\text{H}}_2\text{S}$

The equation is balanced.
