Question

Complete the following word equation and write balanced molecular equations for the same : $\mathrm{Lead}\left(\mathrm{II}\right)\mathrm{sulphide}+\mathrm{Hydrochloric}\mathrm{acid}(\mathrm{dil}.)\to$

Answer 1

Word Equation :

• $\mathrm{Lead}\left(\mathrm{II}\right)\mathrm{sulphide}+\mathrm{Hydrochloric}\mathrm{acid}(\mathrm{dil}.)\to \mathrm{Lead}\mathrm{chloride}+\mathrm{Hydrogen}\mathrm{Sulphide}$.

Molecular Equation :

• $\mathrm{PbS}\left(\mathrm{s}\right)+2\mathrm{HCl}(\mathrm{dil}.)\left(\mathrm{l}\right)\to {\mathrm{PbCl}}_2\left(\mathrm{s}\right)+{\mathrm{H}}_2\mathrm{S}\uparrow \left(\mathrm{g}\right)$
