5. Consider the following experiment: A block of iron with an initial mass of 50 g is placed in a sealed container of pure oxyge
Vera_Pavlovna [14]

The observation in the illustration remains in accordance with the law of conservation of mass assuming that moisture is present in the container.

<h3>What is the law of conservation of mass?</h3>

The law state that mass can neither be created nor destroyed. However, mass can be converted from one form to another.

In this case, the ion was placed in a container of pure oxygen. Assuming that moisture is present, iron reacts with oxygen to form rust according to the following equation:

4Fe + 3O_2 + 6H_2O --- > 4Fe(OH)_3

The rust formed will weigh more than the initial weight of the iron.

Without the presence of moisture, one can effectively conclude that the observation violates the law of conservation of mass.
