Question

An element L consists of molecules. When L is heated with iron metal, it forms a compound$\mathrm{FeL}$. What chemical term would you use to describe the change undergone by L?

Answer 1

• When L is heated with Iron metal, it forms the compound$\mathrm{FeL}$.
• Here iron metal ($\mathrm{Fe}$) undergoes oxidation and L undergoes reduction.
• The reaction that occurs during the process is:

$\mathrm{Fe}\to {\mathrm{Fe}}^{2+}+2{\mathrm{e}}^{-}$

$\mathrm{Fe}+\mathrm{L}\to \mathrm{FeL}$

Here, the oxidation state of iron metal ($\mathrm{Fe}$) changes from $0to+2$ and it will undergo oxidation.
