gases (sulfur dioxide, carbon dioxide, hydrogen sulfide)

Gases like sulfur dioxide (SO₂), carbon dioxide (CO₂), and hydrogen sulfide (H₂S) are naturally occurring or industrially produced substances with distinct properties. CO₂ is a colorless, odorless gas vital for plant photosynthesis and common in Earth's atmosphere. SO₂ results from burning fossil fuels, contributing to acid rain and respiratory issues. H₂S is a colorless, flammable gas with a foul odor of rotten eggs, produced by decaying organic matter and certain industrial processes, and can be toxic at high concentrations. Understanding these gases helps manage their environmental impact and health risks effectively.
