The chemical equation K2S + O2 -> K2SO3

Detailed information about the chemical equation:

The above equation describes the reaction process between potassium sulfide (K₂S) and oxygen (O₂) to form potassium sulfite (K₂SO₃).

Potassium sulfide (K₂S) is a chemical compound of the sulfide group of potassium. In its pure form, it is a pale yellow, odorless solid.

Oxygen (O₂) is a chemical element in group 16 (chalcogens) of the periodic table.

Potassium sulfite (K₂SO₃) is a chemical compound of the sulfite group of potassium.

Reaction conditions:

The reaction between potassium sulfide and oxygen usually occurs at high temperatures or in environments containing catalysts.

Reaction process:

When potassium sulfide is burned in air or oxygen at high temperatures, it reacts with oxygen to form potassium sulfite.

Phenomenon occurrence:

When the reaction occurs, we can see the solid potassium sulfide disappear and form a white solid, which is potassium sulfite.

Note: This is a general process and the specific nature of the reaction may depend on specific conditions such as temperature, pressure, and the presence of other substances.
