Which of the following is NOT a half reaction?
Which of the following is NOT a half reaction?
Options
- A2 Na(s) → 2 Na⁺(g) + 2e-
- BCl2(g) + 2e- → 2 Cl⁻(g)
- C4 Na(s) + O2(g) → 2 Na2O(s)
- D2NaCl(s) → 2Na+(g) + 2Cl-(g)
Correct answer
C. 4 Na(s) + O2(g) → 2 Na2O(s)
Step-by-step solution
The passage states that half reactions explicitly show the involvement of electrons, and option C is not a half reaction.
