Q: During a chemical reaction, the sum of the masses of the reactants and products remains unchanged. What is this called?
  • A. Law of Constant Proportion
  • B. Principle of Energy Conservation
  • C. Chemical Combination Law
  • D. Mass Conservation Principle
Correct Answer: Option D - During a chemical reaction, the sum of the masses of the reactants and products remains unchanged. This is called the principle of conservation of mass. Mass can neither be created nor be destroyed, it can be transferred from one body to another.
