Pb is +2 on the left, zero on the right. That's a gain of electons and that is xxxxx.
tonnemoles PbO = 44.6/molar mass PbO
Convert tonne mols PbO to tonne mols C
Now convert tonne mols C to tonnes. toones = tonne mols C x atomic mass C.
The equation for the reaction that occurs when lead(II) oxide is heated with coke in a blast furnace is: 2PbO+c -->2Pb+CO2
(i)State, with a reason, whether PbO is oxidised or reduced in this reaction.
(ii)Calculate the minimum mass, in tonnes, of coke needed to react with 44.6 tonnes of lead(II) oxide.
[1 tonne=10^6g]

Mass of coke needed=.................tonnes
