Answer:
D. The number of atoms remains the same.
Explanation:
In a chemical reaction the total mass of all the substances taking part in the reaction remains the same. Also, the number of atoms in a reaction remains the same. Mass cannot be created or destroyed in a chemical reaction.
In a chemical reaction, the number of atoms remains the same.
• A process in which one or more substances known as reactants are transformed to one or more distinct components, that is, the products is known as a chemical reaction.
• The sum of the mass of all the substances taking part in a chemical reaction stays the same in a chemical reaction.
• The number of atoms in a reaction also stays similar.
• The mass cannot be destroyed or created in a chemical reaction.
• No new atoms are produced or destroyed in a chemical reaction, the bonds between the atoms are dissociated and realigned as novel bonds to produce the novel product. It is based on the law of conservation of matter.
Thus, the correct answer is option D, that is, the number of atoms remains same.
