Identify the correct statement about a chemical reaction:

A. The reactants and products are different substances.
B. The reactants have less energy than the products.
C. The temperature of the container increases.
D. No change in energy occurs.



Answer :

Final answer:

Chemical reactions involve the transformation of reactants into products with energy changes, often involving heat transfer.


Explanation:

The reactants and products are different substances. This signifies a chemical reaction has occurred, where the initial substances (reactants) transformed into new substances (products). In chemical reactions, the energy of the product is less than the energy of the reactants, leading to energy changes during the reaction. Heat is absorbed by reactants to form products, illustrating energy transfer in exothermic reactions.
