Question

Matter is neither __________ nor __________ during a chemical reaction.

• A. created
• B. destroyed

Answer 1

Answer: Created, destroyed

• The law of conservation of mass asserts that the reactants and products have the same mass before and after a chemical reaction. This means that mass cannot be formed or destroyed in a chemical process; in other words, the total mass of the reaction remains constant.
• Therefore, the matter is neither created nor destroyed during a chemical reaction.
