Question

Write the balanced equations for the preparation of the following compounds (as the major product) starting from iron and using only one other substance:

Iron (ll) sulfide.

Answer 1

• Iron(ll) sulfide can be prepared by a reaction of iron metal and sulfur.
• The chemical formula of Iron(ll) sulfide or Ferrous sulfide is $FeS$.
• Hence the balanced chemical equation is,
• $\underset{Iron}{Fe\left(s\right)}+\underset{Sulfur}{S\left(s\right)}\stackrel{∆}{\to }\underset{Iron\mathit{\left(}II\mathit{\right)}\mathit{}sulfide}{FeS\left(s\right)}$.
• The above reaction is an example of a combination reaction in which iron and sulfur react to form a single compound i.e. Iron(ll) sulfide.
