Verified step by step guidance1
Understand the Law of Conservation of Mass: This law states that mass is neither created nor destroyed in a chemical reaction. It implies that the mass of the reactants must equal the mass of the products.
Analyze each statement: Begin by examining each statement provided in the problem to determine its alignment with the Law of Conservation of Mass.
Evaluate the statement 'Mass can be created or destroyed in a chemical reaction': This statement contradicts the Law of Conservation of Mass, as the law explicitly states that mass cannot be created or destroyed.
Consider the statement 'The mass of reactants equals the mass of products in a chemical reaction': This statement is true according to the Law of Conservation of Mass, as it reflects the principle that mass is conserved.
Review the statement 'Atoms are rearranged but not lost in a chemical reaction': This statement is consistent with the law, as it describes the rearrangement of atoms without any loss, maintaining the total mass.
