Question

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

${\mathrm{FeCl}}_2+\mathrm{Zn}\stackrel{∆}{\to }$

Answer 1

Part 1:

Balance equation:

• A balanced chemical equation has the same number of atoms on the reactant and product sides for each element involved in the reaction.

The balanced equation is:

$$\begin{gathered} {\mathrm{FeCl}}_2+\mathrm{Zn}\to {\mathrm{ZnCl}}_2+\mathrm{Fe} \\ \mathrm{Iron}\mathrm{chloride}\mathrm{Zinc}\mathrm{Zinc}\mathrm{chloride}\mathrm{Iron} \end{gathered}$$

Part 2:

Type of reaction: This is a displacement reaction.

Displacement reaction:

• Displacement reaction is also called substitution reaction.
• These are the reactions involving the displacement of an element from a compound by another element that takes its place.
• The ability of an element to displace another is determined by its relative position in an electrochemical series.
