Answer
In a chemical reaction, substances interact to form one or more new substances.
Solution
In a chemical reaction, the correct statement is:
© Substances interact to form one or more new substances.
Here’s a brief explanation of each option:
(A) This statement is incorrect because, in a chemical reaction, substances change not only in appearance but also in their chemical composition.
(B) While substances can change states (solid, liquid, gas) during a reaction, this statement does not encompass the essence of a chemical reaction, which involves the formation of new substances.
© This statement is correct as it accurately describes the fundamental nature of a chemical reaction, where reactants interact to produce products that are chemically different from the original substances.
(D) This statement is incorrect because, in a chemical reaction, atoms are neither created nor destroyed; they are rearranged to form new substances, in accordance with the law of conservation of mass.

When a chemical reaction occurs, substances interact at the molecular level, leading to the rearrangement of atoms and bonds. This interaction results in the formation of one or more new substances with distinct properties. It’s like a recipe where ingredients combine to create a delicious dish that’s different from its individual parts.
It’s important to remember that during these reactions, atoms are not created or destroyed—just transformed! Think of them as actors in a play, changing roles but remaining in the scene. This fundamental law of conservation of mass keeps the universe balanced while allowing for all the exciting chemical transformations we observe!
