Question
In a reaction where 10 g of reactants produce 10 g of products, what does this demonstrate about mass in chemical reactions?
Answer
This demonstrates that the mass of the products is equal to the mass of the reactants, supporting the law of conservation of mass.
Explanation
The question assesses the student's ability to apply the concept of conservation of mass to a specific example. A strong answer shows comprehension of how mass is conserved in chemical reactions.
Common mistake
Mass Misunderstanding
Students often think that the mass of products can differ from the mass of reactants in a chemical reaction.
Emphasize that according to the law of conservation of mass, the total mass of reactants must equal the total mass of products in a closed system.
