Per NCERT, what does Dalton's theory say about the COMBINING ratios of atoms in a compound?
AAtoms combine in SIMPLE, WHOLE-NUMBER ratios to form compounds (e.g. 1:1, 1:2, 2:3)
BAtoms combine in fractional ratios
CAtoms combine in random ratios
DCombining ratios are unpredictable
Answer & Solution
Correct answer: A. Atoms combine in SIMPLE, WHOLE-NUMBER ratios to form compounds (e.g. 1:1, 1:2, 2:3)
Per NCERT §9.3, Dalton: atoms combine in simple integer ratios. This explains the law of constant proportions (Proust).
