The combustion reaction that can be identified is Al₂S₃ + 2Al + 3S and represents the combustion of aluminum sulfide (Al₂S₃), a compound of aluminum and sulfur.
Aluminum sulfide (Al₂S₃) reacts with oxygen (O₂) from the air to form aluminum oxide (Al₂O₃) and sulfur dioxide (SO₂). Aluminum oxide (Al₂O₃) is a white, solid compound that is often formed as a byproduct of aluminum smelting. which has found applications in various industrial applications, such as ceramics, pigments, and refractories.
Sulfur dioxide (SO₂) is a colorless gas with a pungent odor and is a major air pollutant that can cause respiratory problems and acid rain. Heat is released during the combustion reaction, which can be harnessed for various purposes, such as generating electricity or powering industrial processes.
