A. Bonds of the reactants are broken, and bonds of the products are formed.
B. Bonds of the reactants are formed, and bonds of the products are broken.
C. The bonds of both the reactants and the products are broken.
D. The bonds of both the reactants and the products are formed.

Respuesta :

Answer: The correct option is A.

Explanation: In a chemical reaction, reactants react to form a number of products.

For the formation of products, the bonds of the individual reactants must be broken and the bonds of the products must be formed.

For example: Formation of water from hydrogen gas and oxygen gas. Reaction follows:

[tex]2H_2(g)+O_2(g)\rightarrow 2H_2O(l)[/tex]

The Bonds of hydrogen and oxygen molecule are broken and new bonds between hydrogen and oxygen atoms are formed to give water molecule.

The correct answer is A. Bonds of the reactants are broken, and bonds of the products are formed.
