Answer:
Have a good day
Explanation:
Proper Question: Which expression best represents the law of conservation of mass?
(a) mass of reactants > mass of products
(b) mass of reactants < mass of products
(c) mass of reactants = mass of products
(d) mass of reactants → mass of products
Answer: The expression which best represents the law of conservation of mass is Mass of reactants = Mass of products. Hence the correct option is (c) mass of reactants = mass of products.
Explanation:
→ The law of conservation of mass states that the mass can neither be created nor be destroyed. The overall mass of the mixture remains constant during a chemical reaction.
→ The mass of each substance as well as the overall mass of the complete mixture remains constant during a chemical reaction. The mass of each element remains constant during a chemical reaction.
→ Since the mass of each element is constant during a chemical reaction therefore a proper chemical reaction must always be balanced. The mass of an element on the reactants side must always be equal to the mass of the element on the products side.
→ It can be said that during a chemical reaction the overall mass of the reactants must always be equal to the overall mass of the products.
∴ Mass of reactants = Mass of products
Therefore the expression which best represents the law of conservation of mass is Mass of reactants = Mass of products. Hence the correct option is (c) mass of reactants = mass of products.
