Answer: Out of the given options bonds connecting atoms in reactants break, and bonds connecting atoms in products form are the changes which takes place when a chemical change occurs.
Explanation:
A change that leads to the change in chemical composition of a substance is called a chemical change.
For example, ![2NH_{3} \rightarrow N_{2} + 3H_{2}](https://tex.z-dn.net/?f=2NH_%7B3%7D%20%5Crightarrow%20N_%7B2%7D%20%2B%203H_%7B2%7D)
Here, bond between the reactant atoms nitrogen and hydrogen is broken down.
On the other hand, bond connecting the products that is
and
is formed.
Thus,, we can conclude that out of the given options bonds connecting atoms in reactants break, and bonds connecting atoms in products form are the changes which takes place when a chemical change occurs.
