Question

According to law of conservation of mass, during a chemical reaction:

• A. that matter can be created but not destroyed in a chemical reaction.
• B. that matter can neither be created nor be destroyed in a chemical reaction.
• C. that matter cannot be created but destroyed in a chemical reaction.
• D. that matter can be created as well as destroyed in a chemical reaction.

Answer 1

The correct option is B

that matter can neither be created nor be destroyed in a chemical reaction.

According to the law of conservation of mass, the mass before and after a chemical reaction remains the same. So the mass of the reactants is equal to the mass of the products. Something that have mass and occupies space is known as matter. Thus, as per the law of conservation of mass, matter can neither be created nor be destroyed in a chemical reaction.
