Per NCERT §7.3.2, the TWO methods used to balance redox reactions are which?
AMass action and equilibrium
BLimit and ratio
COxidation-number and half-reaction
DTrial-and-error and inspection
Answer & Solution
Correct answer: C. Oxidation-number and half-reaction
NCERT §7.3.2: two standard methods are oxidation-number balancing and half-reaction (ion-electron) balancing.
