When iron pyrite (FeS₂) burns, it undergoes a chemical reaction with oxygen, resulting in the formation of iron oxide (Fe₂O₃) and sulfur dioxide (SO₂) gas. The burning process releases heat and can produce a bright flame due to the oxidation of sulfur. This reaction can also lead to the generation of sulfuric acid when SO₂ reacts with moisture in the atmosphere, contributing to environmental concerns such as acid rain.
