Final answer:
The Law of Conservation of Mass states that matter is neither created nor destroyed during any chemical reactions, ensuring the mass of reactants and products remains equal.
Step-by-step explanation:
The law that states that matter is neither created nor destroyed in any chemical reaction is known as the Law of Conservation of Mass. This fundamental principle was formulated by French chemist Antoine Lavoisier in 1789. The Law of Conservation of Mass is a cornerstone in the field of chemistry, explaining that during a chemical reaction, the total mass of the reactants equals the total mass of the products.
It implies that matter can change forms, from solids to liquids to gases and vice versa, but the total mass remains constant. For instance, when wood burns, the mass of the resulting soot, ashes, and gases is equal to the mass of the original wood and oxygen that reacted.
