Answer : The value of diffusion coefficient is, 
Explanation :
Formula used :
where,
D = diffusion coefficient = ?
= 
= 
R = gas constant = 8.314 J/mol.K
T = temperature = 
Now put all the given values in the above formula, we get:
Thus, the value of diffusion coefficient is,
It means that 22.5×10^5 J of heat is required to change 1 kg of water into steam.
Latent heat of vaporization is amount of energy required to change 1 gram (in this example 1 kilogram) of material from the liquid to the gaseous state at its boiling point.
Boiling point of the water is 100°C.
Joule (J) is the standard unit for energy (in this example heat).
Evaporization is phase change process in which the water changes from a liquid to a gas (water vapor). Fore example, solar radiation can be the source of energy for evaporation.

Answer:
The Chemical formula of sodium is Na.
The Chemical formula of oxide is O.
Explanation:
Therefore we know that the term 'valency' is called as the combining capacity of an atom of an element.
So by taking the valency of Sodium and Oxide, we get
Sodium with valency '1' and Oxide with valency '2'.
Na O
1 2
When you cross over you get 'Na2O' as the formula for sodium oxide.
Hope this is helpful for you!
