E)none of the above

Question

What is the balanced oxidation half-reaction for the following unbalanced redox reaction: 
A)Ca → + 2 
B) → Ag + 
C)2 + Ca → 
D) + 2 → 2Ag 
E)none of the above

Quizplus · Accepted Answer

The given redox reaction can be split into two half-reactions, oxidation and reduction. For this reaction, we can identify that the calcium (Ca) is being oxidized and the Ag+ ion is being reduced. 
Thus, the balanced oxidation half-reaction for this reaction is:
Ca → Ca2+ + 2 e-
Option A correctly represents the balanced oxidation half-reaction. The other options represent either the reduction half-reaction or a combination of both half-reactions that do not match the given redox reaction.
