D
Law of Conservation of Mass
Verified step by step guidance1
Identify the principle that deals with the conservation of mass in chemical reactions. This principle is known as the Law of Conservation of Mass.
Understand that the Law of Conservation of Mass states that mass is neither created nor destroyed during a chemical reaction. This means the total mass of reactants equals the total mass of products.
Differentiate between the Law of Conservation of Mass and other related principles such as the Law of Definite Proportions, which states that a chemical compound always contains exactly the same proportion of elements by mass.
Recognize that the Law of Multiple Proportions refers to the fact that when two elements form more than one compound, the masses of one element that combine with a fixed mass of the other are in ratios of small whole numbers.
Clarify that the Law of Conservation of Energy is different from the Law of Conservation of Mass, as it deals with energy being conserved in a system, not mass.
