The correct balanced reaction is:-
2 As₂S₃ (s) + 9 O₂ (g) → 2 As₂O₃ (s) + 6 SO₂ (aq)
A balanced chemical equation occurs when the number of the atoms involved in the reactants side is equal to the number of atoms in the products side. In this chemical reaction, nitrogen (N₂) reacts with hydrogen (H) to produce ammonia (NH₃). The reactants are nitrogen and hydrogen, and the product is ammonia. It means to make the number of atoms the same on both the reactants and products side.
