What is the resulting gas when Hydrogen Sulfide (H2S) is combusted with oxygen?

When Hydrogen Sulfide (H2S) is combusted with oxygen, the chemical reaction produces water (H2O) and sulfur dioxide (SO2). During combustion, H2S reacts with oxygen to oxidize the hydrogen and sulfur present in the compound. The balanced chemical equation for this combustion process can be represented as:

2 H2S + 3 O2 → 2 H2O + 2 SO2.

In this reaction, each molecule of hydrogen sulfide contributes hydrogen atoms that combine with oxygen to form water, while the sulfur atoms are oxidized to form sulfur dioxide. This highlights the conversion of both elements in H2S into stable products: water and SO2.

The option that states only water is produced is incorrect because it neglects the formation of sulfur dioxide, which is a significant product of H2S combustion. Similarly, options that suggest hydrogen or carbon dioxide as products do not align with the expected outcomes of this reaction as they either do not account for all the reactants correctly or misidentify the products of burning hydrogen sulfide.
