One of the following does not happen during a chemical reaction. This is:(a) Breaking of old chemical bonds and formation of new chemical bonds(b) Formation of new substance with entirely different properties(c) Atoms of one element change into those of another element to form new products(d) A rearrangement of atoms takes place to form new products
Correct Answer: (c) Atoms of one element change into those of another element to form new products
Explanation: It is not atoms but bonds between the atoms that break and rejoin to form new products during a chemical reaction. Atoms of elements can rearrange but cannot change into other elements.
