The equation is 4Al + 3O2 -> 2Al2O3.

Detailed information about the equation 4Al + 3O₂ -> 2Al₂O₃:
The above chemical equation describes the reaction between the metal aluminum (Al) and oxygen (O₂) to form the chemical compound aluminum oxide (Al₂O₃). According to this ratio, 4 moles of aluminum will react with 3 moles of oxygen to produce 2 moles of aluminum oxide.

Reaction conditions:
The reaction occurs easily at high temperatures. Aluminum needs to be heated to start the reaction process.

Reaction process:
When aluminum is heated and comes into contact with oxygen, the aluminum atoms react with oxygen to form aluminum oxide. This process is an oxidation process because aluminum (Al) has accepted additional oxygen (O₂) to form aluminum oxide (Al₂O₃).

Occurring phenomena:
When the reaction occurs, if conducted under laboratory conditions, you would see the aluminum melt and glow as it reacts with oxygen. The final product, aluminum oxide, is a white solid.
