Please no pictures I want the response typed quenched, gladden you.
The forthcoming unbalanced equation describes the reaction that can happen when control (II) sulfide reacts with oxygen gas to consequence control (II) oxide and sulfur dioxide gas:
PbS + O2 PbO + SO2
Balance the equation and describe in tone the electron exchange(s) that takes establish.
PbS + O2 —————–> PbO + SO2
2PbS + 3O2 —————–> 2PbO + 2SO2
above mentioned is balanced reaction.
in pbS S = -2 avow
in SO2 S = +4 avow
so S oxidized from -2 to +4 avow.
in reactants O = 0 avow
in products O = -2 avow
so O subdued from 0 to -2
for 1 S 6 electrons exchange.
2 S compromises in reaction so 6 x 2 = 12
12 electrons exchange compromise in the reaction.
