Per NCERT §7.2, a HALF REACTION is best characterised as which kind of equation?
AShows electrons explicitly
BShows only spectators
CHas no atom balance
DHas no charge balance
Answer & Solution
Correct answer: A. Shows electrons explicitly
NCERT §7.2: half-reactions show e⁻ explicitly — one is oxidation, the other reduction. Sum gives full redox equation.
