Answer 2

Why does the number of atoms remain constant during a chemical reaction?

During a chemical reaction, the number of atoms remains constant due to the law of conservation of mass. This fundamental principle states that matter cannot be created or destroyed in a chemical reaction, only rearranged. Therefore, the total number of atoms before and after the reaction must be the same.

When a chemical reaction occurs, the atoms of the reactants rearrange to form new compounds or molecules, known as the products. However, the total number of atoms on both sides of the reaction equation remains unchanged. This is because chemical reactions involve the breaking and forming of chemical bonds, but the atoms themselves are not created or destroyed.

For example, let's consider the reaction between hydrogen gas (H2) and oxygen gas (O2) to form water (H2O). The balanced chemical equation for this reaction is:

2H2 + O2 → 2H2O

In this reaction, there are four hydrogen atoms and two oxygen atoms on the left side (reactants), and four hydrogen atoms and two oxygen atoms on the right side (products). The total number of atoms (hydrogen + oxygen) remains the same before and after the reaction.

This principle holds true for all chemical reactions. The law of conservation of mass ensures that the total mass and the total number of atoms in a closed system remain constant throughout a chemical reaction.
