Understand the Law of Conservation of Mass: This law states that mass is neither created nor destroyed in a chemical reaction. Therefore, the mass of the reactants must equal the mass of the products.
Analyze the given statements: We need to determine which statement aligns with the Law of Conservation of Mass.
Evaluate the first statement: 'The total mass of the products is greater than the total mass of the reactants.' This contradicts the law, as it suggests mass is created.
Evaluate the second statement: 'Mass is lost as energy during the reaction.' This implies mass is destroyed, which also contradicts the law.
Evaluate the third statement: 'The total mass of the reactants equals the total mass of the products.' This is consistent with the Law of Conservation of Mass, making it the correct statement.
