The Reaction of Magnesium with Nitrogen: A Fiery Experiment

TLDRIn this video, we explore an experiment that demonstrates the reaction between magnesium and nitrogen. By creating a pyramid of magnesium granules and setting them alight in the presence of air, we observe the formation of magnesium oxide. Enclosing the burning magnesium in a beaker causes it to react with the nitrogen, producing a captivating display of glowing, erupting plumes. The resulting magnesium nitride can be further reacted with water to produce ammonia. The experiment highlights the high activation energy required for the magnesium-nitrogen reaction and the release of heat during the process. We also address the question of why some previous attempts at this experiment failed and explore the chemistry behind the reaction.

Key insights

🔥The reaction between magnesium and nitrogen requires high activation energy due to the strong bond between nitrogen atoms.

🌋Burning magnesium in the presence of nitrogen produces plumes of glowing fire, resembling an erupting volcano.

💡The reaction between magnesium and nitrogen produces a blue-green flame due to the possible recombination of nitrogen atoms.

🔬The experiment can be enhanced by using larger magnesium granules and providing sufficient heat to initiate the reaction.

🧪Magnesium nitride, the product of the magnesium-nitrogen reaction, can be further reacted with water to produce ammonia.

Q&A

Can the reaction between magnesium and nitrogen occur spontaneously?

—No, the reaction requires a high activation energy and heat to initiate.

Why does the beaker fill with white smoke during the experiment?

—The white smoke is finely divided magnesium oxide, formed as a byproduct of the reaction.

What causes the blue-green flame during the reaction?

—The blue-green flame is possibly due to the recombination of nitrogen atoms in the presence of the burning magnesium.

Why did previous attempts at the experiment fail?

—Previous attempts may have failed due to insufficient heat or the use of magnesium ribbon instead of granules.

Can magnesium nitride be used for other chemical reactions?

—Yes, magnesium nitride can be reacted with water to produce ammonia.
