Per NCERT, what does Dalton's theory say about chemical reactions at the atomic level?
AAtoms are created when needed
BAtoms are destroyed during reactions
CAtoms are merely REARRANGED, COMBINED, or SEPARATED — they are never created or destroyed during a chemical reaction
DReactions create energy from nothing
Answer & Solution
Correct answer: C. Atoms are merely REARRANGED, COMBINED, or SEPARATED — they are never created or destroyed during a chemical reaction
Per NCERT §9.3, Dalton: atoms rearrange in fixed integer ratios during reactions; never created/destroyed. This explains Lavoisier's law of conservation of mass.
