4 beaker and 1 st beaker

Answer 2

Answer:

Rusting of the nail will take place in beaker B which is filled with water and kept open without any rubber stopper.

The iron nail will get rusted because rusting occurs on the presence of two condition :

i ) Presence of oxygen in the air.

ii) Presence of water around the nail but it can be water vapours also which are present in air.

Reaction :

4 Fe + 3O2 + 6H2O → 4Fe(OH)3

Some ways to prevent rusting :

i) Paint the meatal or iron nail with any durable acrylic paints to prevent oxidation.

ii ) Avoid contact of moisture or water with the nail or any metal that reacts with water.

iii) Coat the metal with oil or grease which will prevent the oxidation of the metal.

iv) Donot make use of pure metls rather form alloys of iron , copper by mixing them with nickel , zinc etc to form alloys like brass , bronze etc which are not easily rusted.

Hope it helps you!
