What is the difference between sulfur and sulfur dioxide?
Sulfur is an element, and sulfur dioxide (SO2) is a compound containing sulfur and oxygen.
No, sulfur is an element and sulfur dioxide is a gaseous compound. Sulfur dioxide is the combustion product of sulfur in an oxygen atmosphere (S+O2 --> SO2) Where sulfur is an element, sulfur dioxide is a compound and where sulfur is an insoluble yellow solid, sulfur dioxide is a colorless soluble gas.
What is the chemical equation to sulfur dioxide when it reacts with oxygen gas to produce sulfur trioxide gas?
Basically, sulfur dioxide is a acidic gas. As acid reacts with alkali, carbonates and metals, all 3 are actually ideal to remove sulfur dioxide. However, in the context of removing sulfur dioxide due to air pollution, reacting sulfur dioxide with alkali and carbonate would be more appropriate. For example, removing sulfur dioxide with calcium carbonate would result in calcium sulfate, water and carbon dioxide.
