All mass is conserved in a chemical reaction. What law does this represent?
A
Dalton's Atomic Theory
B
Law of Conservation of Mass
C
Law of Multiple Proportions
D
Law of Definite Proportions
Verified step by step guidance1
Understand that the problem is asking about a fundamental principle in chemistry related to mass during chemical reactions.
Recall that the Law of Conservation of Mass states that mass is neither created nor destroyed in a chemical reaction; the total mass of reactants equals the total mass of products.
Recognize that Dalton's Atomic Theory, Law of Multiple Proportions, and Law of Definite Proportions describe different concepts related to atoms and compounds, but do not specifically address mass conservation.
Identify that the statement 'All mass is conserved in a chemical reaction' directly corresponds to the Law of Conservation of Mass.
Conclude that the correct law represented by the statement is the Law of Conservation of Mass.
