Question #ba857

Answer 1

It depends on which kind of lead oxide you have made.

Explanation:

Lead will react with oxygen to produce lead oxide. There are two types of lead oxide and we need to know which one is produced.

First possibility :
lead + oxygen ----> lead (II) oxide
`2 Pb + O_2 rarr 2PbO`

For every 2 moles of `Pb`, we need 1 mole of `O_2`. So if we have .66 moles of `Pb`, we need half that number of moles of `O_2` in order to not have any `Pb` or `O_2` left over. (This will also produce 2 moles of `PbO_2`)

Second possibility :
lead + oxygen ----> lead (IV) oxide
`Pb + O_2 rarr PbO_2`

For every 1 mole of `Pb`, we need 1 mole of `O_2`. So if we have .66 moles of `Pb`, we need the same number of moles of `O_2` in order to not have any `Pb` or `O_2` left over. (This will also produce 1 mole of `PbO_2`)
