lead sulfide reacts with oxygen gas to produce lead oxide and sulfur dioxide. if 0.500 moles of o2 were consumed using this chemical reaction, how many moles of lead oxide would be produced

Respuesta :

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)
