उत्तर
A is false but R is true.
Explanation:
Assertion (A) is false because atoms of one element never change into atoms of another element during a chemical reaction; they only rearrange their chemical bonds. Reason (R) is true because chemical reactions fundamentally rearrange these existing atoms to create entirely new substances that exhibit completely different properties.
