How to balance _h2s+ _o2 = _h2o+ _s

goldfiish [28.3K]

Answer:

2H₂S + 1O₂ → 2H₂O + 2S

Explanation:

SOLUTION :-

Balance it by using 'hit & trial' method , and you'll get the answer :-

2H₂S + 1O₂ → 2H₂O + 2S

VERIFICATION :-

In reactant side of equation :-

Number of atoms in H = 2×2 = 4
Number of atoms in S = 2×1 = 2
Number of atoms in O = 1×2 = 2

In product side of equation :-

Number of atoms in H = 2×2 = 4
Number of atoms in O = 2×1 = 2
Number of atoms in S = 2×1 = 2

Number of atoms of each element is equal in both reactant & product side of equation. Hence , the equation is balanced.
