A few drops of water are added to hydrolyse any magnesium nitride, Mg 3 N 2, that may have formed and the crucible is reheated to remove the water and decompose any Mg (OH) 2 to MgO and H 2 O. When isolating argon, William Ramsay passed dry air over copper to remove oxygen and over magnesium to remove the nitrogen, forming magnesium nitride. Indeed, temperature is an important factor for this reaction and the reaction carries at a specific temperature. rev2023.4.17.43393. There is agreement, however, that Mg3N2can be synthesised by direct reaction of the elements and the consensus is that the reaction on a lab scale completes in four to five hours at 800 850oC.

It has high corrosion resistance which makes it very useful in the production of other nitride compounds. Reaction of magnesium with nitrogen gas Magnesium reacts with atmospheric nitrogen to form magnesium nitride (the structure is shown below). We can be certain that the reaction causes a reduction in entropy (a gas is turned into a solid), so now we can just check the enthalpy of formation. In fact, when magnesium is burned in air, some magnesium nitride is formed in addition to the principal product, magnesium oxide. By John Brennan. (b) The second step is the formation of solid calcium hydroxide as the only product from the reaction of the solid calcium oxide with liquid water. The solution to this paradox is the quoted adiabatic temperature assumes a stoichiometric mixture. What mass of nitrogen is formed by the decomposition of 2.6 kg of .

Several experiments were conceived and performed to answer our question. As you can see, magnesium metal does react directly with molecular nitrogen ($\ce{N2}$) when burned in air. The melting point of magnesium nitride is 1500C and when heated beyond this temperature, it results in decomposition of the powder and forming of a gas of nitrogen. It can also be used as a catalyst as it works really well during specific reactions to fork nitride compounds out of them. At high temperatures, Mg will also combine with nitrogen in air to form magnesium nitride. The Mg reacts with O2in the air and a white residue of MgO is left. When the magnesium is not allowed sufficient oxygen, some magnesium oxide, Mg3N2, forms. John L. Porter, Preparation of magnesium nitride, United States Patent 2487474.
