In the redox reaction: 3H₂S + 2HNO₃ → 3S + 2NO + 4H₂O, which element is being oxidized?
Nitrogen
Oxygen
Sulfur
Hydrogen
📝 Detailed explanation
The oxidation state of Sulfur in H₂S is -2 and it increases to 0 in elemental Sulfur. Since the oxidation state increases (loss of electrons), Sulfur is oxidized.
