Question

Complete and balance the following equation and also state the type of reaction that is taking place :

$\mathrm{Fe}+{\mathrm{Cl}}_2\to$

Answer 1

Part 1: When Iron reacts with Chlorine we get Ferrous chloride.

The equation of the reaction can be written as-

$\underset{\mathrm{Iron}}{\mathrm{Fe}\left(\mathrm{s}\right)}+\underset{\mathrm{Chlorine}\mathrm{gas}}{{\mathrm{Cl}}_2\left(\mathrm{g}\right)}\to \underset{\mathrm{Ferric}\mathrm{Chloride}}{{\mathrm{FeCl}}_3\left(\mathrm{s}\right)}$

Balancing-

• We multiply the Chlorine molecule in the reactant part by 3.
• To balance 6 atoms of chlorine in the reactant part we multiply Ferrous chloride in the product part by 2.
• Multiply Iron in the reactant part by 2.
• Hence, the balanced equation is-

$\underset{\mathrm{Iron}}{2\mathrm{Fe}\left(\mathrm{s}\right)}+\underset{\mathrm{Chlorine}}{3{\mathrm{Cl}}_2\left(\mathrm{g}\right)}\to \underset{\mathrm{Ferrous}\mathrm{chloride}}{2{\mathrm{FeCl}}_3\left(\mathrm{s}\right)}$

Part 2: Type of Reaction:

It is an example of a synthesis reaction.

Synthesis reaction- A synthesis reaction or direct combination reaction is a type of chemical reaction in which two or more simple substances combine to form a more complex product.

• The reactants may be elements or compounds.
• The product is always a compound.
