The equation 2Mg3N2 -> 3Mg2N2 + 2N2 + 2O2

1. Detailed information about the equation 2Mg₃N₂ -> 3Mg₂N₂ + 2N₂ + 2O₂ ->
   This chemical equation represents the decomposition of magnesium nitrite (Mg₃N₂) after being affected by high temperatures. As a result, this compound decomposes into magnesium nitrate (Mg₂N₂), nitrogen (N₂), and oxygen (O₂).

2. Reaction conditions
   For the reaction to occur, a high temperature condition is needed.

3. Reaction Process
   When Mg₃N₂ is affected by high temperatures, the bonds between magnesium and nitrogen atoms are broken, forming Mg₂N₂, N₂, and O₂.

4. Phenomena that occur
   When the reaction occurs, there is a phenomenon of releasing nitrogen and oxygen gases. If the reaction is carried out in the laboratory, it can be observed that the initial compound disappears, replaced by the appearance of new substances. This reaction also releases heat, so the increase in temperature can be felt. However, this reaction should not be performed externally as it can lead to danger due to heat release and gas release.

Note: The equation you provided is not entirely accurate, you might be confused as O₂ is not in the product. The correct equation might be 2Mg₃N₂ -> 6Mg + 2N₂ -> .
