Question

By using iron metal only, how will you prepare:

Iron (II) Sulphide.

Answer 1

• When iron is heated with sulphur then iron sulphide ($\mathrm{FeS}$) is formed.

The balanced equation is:

$$\begin{gathered} {\mathrm{Fe}}_{\left(\mathrm{s}\right)}+{\mathrm{S}}_{\left(\mathrm{s}\right)}\stackrel{∆}{\to }{\mathrm{FeS}}_{\left(\mathrm{s}\right)} \\ \mathrm{Iron}\mathrm{Sulphur}\mathrm{Iron}\left(\mathrm{II}\right)\mathrm{sulphide} \end{gathered}$$
