Per NCERT §Balancing a chemical equation, can the SUBSCRIPTS in chemical formulas be changed to balance an equation?
ANo — only the coefficients can be adjusted; changing subscripts would change the chemical identity of the compound
BSubscripts and coefficients are interchangeable
CYes, but only for water
DYes, subscripts can be changed freely
Answer & Solution
Correct answer: A. No — only the coefficients can be adjusted; changing subscripts would change the chemical identity of the compound
Per NCERT §Balancing, subscripts identify the molecule and CANNOT be changed. Only coefficients vary.
