Answer:
number 3 i think
Explanation: im sorry if im wrong
All options are as follow,
<span>A. PbS + O2→ PbO + SO</span>₂<span>
B. PbS + 2O</span>₂<span>→ PbO + 2SO</span>₂<span>
C. 2PbS + 2O</span>₂<span>→ 2PbO + 2SO</span>₂<span>
D. 2PbS + 3O</span>₂<span>→ 2PbO + 2SO</span>₂<span>
E. 3PbS + 3O2→ 2PbO + 2SO2
Option A is not balanced because the number of oxygen atoms are greater at right hand side.
</span><span>
Option B is not balanced because the number of oxygen are less at right hand side and number of sulfur atoms are greater at right hand side.
Option C is not balanced because the number of oxygen atoms are greater at right hand side.
Option D is Balanced, all elements are balanced at both sides.
Option E is not balanced because number of Lead and Sulfur atoms are greater at right hand side.
Result:
Equation in Option D is balanced and correct answer.
