When battery discharge / delivering current the lead at the anode is oxidized
that is ;
pb---->pb+ 2e-
since the lead ions are in presence of aquous sulfate in insoluble lead sulfate precipitate onto the electrode
the overall reaction at the anode is therefore
Pb + SO4^2- ---> PbSO4 + 2e-

how many liters of O2 are needed to produce 5.62 g of SO2 in the following reaction? 4FeS2+11O2 ->2Fe2O3+8SO2

Liula [17]

8moles of SO_2 need 11mol O_2

1mol need=11/8=1.4molO_2

Moles of sO_2

$\\ \rm\hookrightarrow \dfrac{5.62}{64}=0.1$

Moles of O_2

1.4(0.1)=0.14mol

We know

1mol at STP=22.4L
1.4mol=0.14(22.4)=3.13L O_2
