According to the Law of Conservation of Mass, what is conserved during a chemical reaction?
A
The total mass of the reactants and products
B
The temperature of the reactants
C
The volume of the system
D
The number of molecules
Verified step by step guidance1
Understand the Law of Conservation of Mass: It states that mass cannot be created or destroyed in a chemical reaction.
Identify what is conserved: Since mass is neither created nor destroyed, the total mass of the reactants must equal the total mass of the products.
Analyze other options: Temperature, volume, and number of molecules can change during a reaction, so they are not conserved.
Conclude that the correct conserved quantity during a chemical reaction is the total mass of the reactants and products.
Summarize: The Law of Conservation of Mass ensures that the sum of the masses before and after the reaction remains constant.
