How many total electrons are transferred during the following redox reaction?

4 P(s) + 5O2(g) –> 2P2O5

Expert Answer

Answer

4 P(s) + 5O2(g) –> 2P2O5

oxidation number of P changes from 0 to +5 , so that each P-atom loses 5 electrons.and total 4 P – atoms lose 20 electrons. and same no of electrons is gained by 10 O-atoms.

No of electrons transfered = 20 electrons
