Lead is normally obtained from PbS which is first converted to Pb0 by roasting in a limited supply of air. A further step in the process is: PbO + CO — Pb + СО, Assign an oxidation number to each atom and verify that the total number of electrons lost is equal to the total number gained. Enter the oxidation numbers under each substance in the box corresponding to the element label to the left. If a box is not needed, leave it blank. PbO CO Pb CO2 Pb C For the reaction as written, the total number of electrons lost is and the total number of electrons gained is
