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. Therefore, the mass of the reactants must equal the mass of the products.
Identify the key concept: The total mass of reactants equals the total mass of products. This is the correct statement according to the Law of Conservation of Mass.
Evaluate the given options: Compare each statement with the Law of Conservation of Mass. The statement 'Mass is lost during the reaction process' contradicts the law, as does 'The total mass of reactants is less than the total mass of products' and 'The total mass of products is greater than the total mass of reactants'.
Select the correct statement: Based on the Law of Conservation of Mass, the correct statement is 'The total mass of reactants equals the total mass of products'.
Reflect on the importance: Understanding this law is crucial for balancing chemical equations and predicting the outcomes of chemical reactions.
