He ability to rust is a chemical property of iron. The metal silver does not rust, but eventually a darker substance called tarnish forms on its surface. The chemical properties of copper cause it to become a blue-green color when it is exposed to air
Atoms are the smallest bits of ordinary matter and are made from particles called protons, neutrons and electrons while a An element is a substance that is made entirely from one type of atom
All organic material has decaying Carbon-14 in it. But if plants and animals are still alive, they constantly replace the supply of Carbon in their systems so the amount of Carbon 14 in the system stays constant. Once a plant or animal dies, the Carbon is no longer regenerated and so the Carbon 14 starts to decay.
Answer:
X represents London dispersion forces, and Y represents ion-dipole forces.
Explanation:
London forces occurs between molecules that are normally non-polar (electrically symmetric). It arises from instantaneous dipoles in molecules. It occurs in all substances.
Permanent dipoles are caused by non-symmetric electron distribution in molecules leading to a permanent dipole in the molecule such as in HCl. Interaction between the permanent dipole in these molecules and an ion is called ion-dipole interaction.
Hence; X represents London dispersion forces, and Y represents ion-dipole forces.
