Which of the following statements about oxidation and reduction reactions is true?
A)More than one electron can be transferred in an oxidation and reduction reaction.
B)In a half-reaction,only half of an electron is transferred.
C)Only neutral atoms are formed in oxidation and reduction reactions.
D)A half-reaction is only used for reduction reactions.
E)None of the above are true.

Question

Quizplus · Accepted Answer

In oxidation and reduction reactions, more than one electron can be transferred. This can be seen in reactions like the reduction of oxygen in cellular respiration where 4 electrons are transferred to form water (O2 + 4e- + 4H+ → 2H2O).

Option B is incorrect because a half-reaction involves the transfer of a whole electron.

Option C is incorrect as oxidation and reduction reactions can result in the formation of ions such as in the reaction of sodium with chlorine to form sodium ions (Na+) and chloride ions (Cl-).

Option D is incorrect as half-reactions can be used for both oxidation and reduction reactions.
