The equation MgO + Mg3N2 -> 3MgO + N2.

1. Detailed information about the equation MgO + Mg₃N₂ -> 3MgO + N₂

The above equation describes the chemical reaction process between magnesium oxide (MgO) and magnesium nitride (Mg₃N₂) to form 3 molecules of magnesium oxide and nitrogen.

2. Reaction conditions

This reaction requires high temperature. In practice, it usually occurs when magnesium burns in the air, creating MgO and Mg₃N₂, then Mg₃N₂ continues to react with MgO at high temperature to create additional MgO and N₂.

3. Reaction process

• Step 1: Magnesium burns in the air to create MgO and Mg₃N₂.
• Step 2: Mg₃N₂ continues to react with MgO at high temperature to produce additional MgO and N₂.

4. Occurring phenomena

When the reaction takes place, a bright light phenomenon can be observed due to the combustion process of magnesium. After the reaction is completed, the product obtained is a white solid of MgO.
