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 total mass of reactants before the reaction is equal to the total mass of products after the reaction.
Identify the key components of the law: The law applies to both physical and chemical changes, meaning that in any closed system, the mass remains constant regardless of the type of change occurring.
Evaluate each statement: Analyze each given statement to determine if it aligns with the Law of Conservation of Mass.
Statement Analysis: 'Mass can be created or destroyed in a chemical reaction' contradicts the Law of Conservation of Mass, as the law explicitly states that mass cannot be created or destroyed.
Conclusion: The statement 'Mass can be created or destroyed in a chemical reaction' is not true according to the Law of Conservation of Mass, making it the correct answer to the question.
