Question

Give the balanced chemical equation for the reaction in which, on being heated with chlorine(${\mathrm{Cl}}_2$), iron($\mathrm{Fe}$) forms iron(III) chloride?

Answer 1

Answer

Note: Steps used for finding balanced chemical equation

• Count each type of atom in reactants and products.
• Place coefficients as needed, in front of the symbol or formula to increase the number of atoms or molecules of substances.
• Repeat steps 1 and step 2 until the equation is balanced.

So the balanced chemical equation for the above reaction is given by:

$$\begin{gathered} 2\mathrm{Fe}\left(\mathrm{s}\right)+3{\mathrm{Cl}}_2\left(\mathrm{g}\right)\stackrel{\mathrm{Heat}}{\to }2{\mathrm{FeCl}}_3\left(\mathrm{s}\right) \\ \mathrm{Iron}\mathrm{Chlorine}\mathrm{Ferric}\mathrm{Chloride} \end{gathered}$$
