Question

3. Explain A friend notices that a nail that was left outside for a few month:
seems larger and heavier than it was before. He says the nail is rusting disproves the Law of Conservation of Mass. Explain why he is wrong.

Answer 1

Answer:

water and o2 are binding to it to make rust/mass

Explanation:

Answer 2

According to the law of conservation of mass of reactants before the reaction must be equal to the mass of the product. He is wrong because the nail is undergoing the process of rusting and after the rusting process mass of the product is increasing.

what is the law of conservation of mass?

According to the law of conservation of mass of reactants before the reaction must be equal to the mass of the product.

What is rusting?

Rusting is a form of oxidation. Rust is formed when iron combines with water and oxygen to generate hydrated iron oxide. Which is given by.

$2Fe + 3O_2= Fe_2O_3$

Nail contains iron when combined with oxygen results in the formation of ferrous oxide which is heavier than iron. That's why the mass of the product is more than the mass of reactants. ]

Hence after a few months seems larger and heavier than it was before.
