Question

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

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

Answer 1

Combination reaction:

• Combination is a chemical reaction in which two simpler reactants combine to form a single product.
• Such reactions can be brought by the action of heat, light, pressure, electricity, etc.
• A general combination reaction is represented as
• $\mathrm{A}+\mathrm{B}\stackrel{}{\to }\mathrm{AB}$
• For example, when the iron$\left(\mathrm{Fe}\right)$ is heated in the presence of chlorine gas$\left({\mathrm{Cl}}_2\right)$, it forms ferric chloride$\left({\mathrm{FeCl}}_3\right)$.
• $\underset{\mathrm{iron}}{2\mathrm{Fe}\left(\mathrm{s}\right)}+\underset{\mathrm{chlorine}\mathrm{gas}}{3{\mathrm{Cl}}_2\left(\mathrm{g}\right)}\stackrel{}{\to }\underset{\mathrm{ferric}\mathrm{chloride}}{2{\mathrm{FeCl}}_3\left(\mathrm{s}\right)}$
