Question

A molecule contains 16 atoms and undergoes a chemical change. How does the chemical change affect the total number of atoms of each element?

Answer

They remain the same

Explanation:

As the molecule goes from reactants to products, the number of atoms in the each of the element remains the same.

This is in compliance with law of conservation of matter. The law proposes that “in a chemical reaction, matter is neither created nor destroyed by changed from one form to another”.

So, since no matter is destroyed, the number of atoms during a chemical change remains the same before and after a reaction.

This is applicable to all chemical changes.
