• law of conservation of energy
• law of conservation of mass
• law of conservation of chemicals
• law of entropy

Explanation:

For Question 3: In chemical reactions, substances that undergo a reaction to form new substances are called reactants. Sodium bicarbonate and acetic acid react with each other, so they are reactants.
For Question 4: The principle that matter is not created or destroyed in a chemical reaction, with total mass remaining constant, is defined by the Law of Conservation of Mass.

Answer:
