Answer:
A mole (mol) is the amount of a substance that contains 6.02 × 10 23 representative particles of that substance. The mole is the SI unit for the amount of a substance. There are, therefore, 6.02 × 10 23 water molecules in a mole of water molecules. Water (H2O) is made from 2 atoms of hydrogen and 1 atom of oxygen.
Because of the sea waters density. If an object is less dense than the water it would not float
Iron oxide is rust. So oil would be an inhibitor.

Valence electrons determine the chemical properties of an element and they are the only ones that get involved in chemical reactions with other elements.
