Option C: Sulfur Dioxide is the answer
Hope this helps
Easy!
All you have to do is look at the formula.
Lead Sulfide is PbS
Lead Oxide is PbO
Sulfur Dioxide is SO₂
Oxygen is O₂
You would need to balance out the equation, so it would be PbS + O₂ --> PbO + SO₂.
We can balance this out with the following. 2PbS + 2O₂ --> 2PbO + SO₂.
So 0.500 moles of oxygen would be the same conversion rate for PbO so it would also be 0.500 moles of lead oxide (PbO)
Answer:
1 × 10-¹ moldm-³
Explanation:
Pkw = PH + POH
14 = 13 + POH
POH = 1
so , [OH-] = 1 × 10-¹ moldm-³
