Question

Identify the metal ‘$x$’ present in chlorophyll and write the reaction of this metal with ${\mathrm{N}}_2$.

Answer 1

Part 1: Identifying the metal present in Chlorophyll

• Chlorophyll is a pigment(the process by which light energy is converted into chemical energy) that is required for photosynthesis and is present in all green plants and a few other organisms.
• The metal found in chlorophyll is Magnesium.
• So, element X is Magnesium.

Part 2: Reaction of metal X with nitrogen

• When magnesium combines with nitrogen gas, Magnesium nitride is formed.
• The balanced chemical reaction can be represented as:

$\underset{\mathrm{Magnesium}}{3\mathrm{Mg}\left(\mathrm{s}\right)}+\underset{\mathrm{Nitrogen}}{{\mathrm{N}}_2\left(\mathrm{g}\right)}\to \underset{\mathrm{Magnesium}\mathrm{nitride}}{{\mathrm{Mg}}_3{\mathrm{N}}_2\left(\mathrm{s}\right)}$

Therefore, the metal ‘$x$’ is present in chlorophyll is Magnesium$\left(\mathrm{Mg}\right)$ and the reaction of Magnesium$\left(\mathrm{Mg}\right)$ with ${\mathrm{N}}_2$ is $\underset{\mathrm{Magnesium}}{3\mathrm{Mg}\left(\mathrm{s}\right)}+\underset{\mathrm{Nitrogen}}{{\mathrm{N}}_2\left(\mathrm{g}\right)}\to \underset{\mathrm{Magnesium}\mathrm{nitride}}{{\mathrm{Mg}}_3{\mathrm{N}}_2\left(\mathrm{s}\right)}$.
