Fe is the symbol of the metal iron. This is because the Latin name of iron is Ferrum. Iron shows more than one valency and forms Fe2+ and Fe3+ ions. Fe2+ ion is formed when an atom of iron loses 2 electrons to form a cation and Fe3+ ion is formed when an atom of iron loses 3 electrons to form a cation. For this reason, Fe2+ is known as the ferrous ion.
Therefore, the correct name for the ion Fe2+ is ferrous ion.
V= d/t
v=speed
d=distance
t=time
So v= 422/3
v =140.667m/s
As temperature increases, the particles will gain kinetic energy causing it to move more rapidly and randomly. However, this causes the gas to expand as the particles will have more energy to roam freely. Hence as temperature increases, Volume increases.
This is based on Charles' Law stating that the volume of a gas is directly proportional to its absolute temperature.
