Question

Pb + PbO2 + 2H2SO4 2PbSO4 + 2H2O How many moles of water are produced if 5.43 mol PbO2 are consumed?

Answer 1

5.43 times 2 = 10.86

10.9 is your answer.

Answer 2

Answer: 10.86 moles

Explanation: For the given chemical reaction. 2 moles of lead combines with 2 moles of lead oxide and 2 moles of sulphuric acid to produce 2 moles of lead sulphate and 2 moles of water.

`Pb+PbO_2+2H_2SO_4\rightarrow 2PbSO_4+2H_2O`

1 mole of lead oxide
`(PbO_2)` produces 2 moles of water
`(H_2O)`

Thus 5.43 moles of lead oxide
`(PbO_2)` produces =
`(2)/(1)* 5.43=10.86` moles of water
`(H_2O)`
