How to balance _h2s+ _o2 = _h2o+ _s
goldfiish [28.3K]

Answer:

<u>2</u>H₂S + <u>1</u>O₂ → <u>2</u>H₂O + <u>2</u>S

Explanation:

<u>SOLUTION :-</u>

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

<u>2</u>H₂S + <u>1</u>O₂ → <u>2</u>H₂O + <u>2</u>S

<u></u>

<u>VERIFICATION :-</u>

<em>In reactant side of equation :-</em>

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

<em>In product side of equation :-</em>

  • 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.
