Answer 1

Answer:

activity of a iron rod and a stone attached with it and we get the result

Answer 2

Take some iron filling (particles of iron which is not rusted) take 3 test tubes:

in 1st test tube add water and oil

in 2nd test tube add water

and keep the 3rd test tube dry (nothing in it)

Keep the test tubes in safe place and observe it..

RESULT: we will see that the iron fillings in the 2 test tube get rusted and in the other test tubes it remains the same.

This will prove rusting of iron requires both air and water..
