e of diffusion varies with the TEMPERATURE.They are directly proportional to each other.The more the temperature, the more the diffusion rate. This is because when SOMETHING is hot, its particles vibrate faster. When they vibrate more, there will be easy movement and hence , diffusion will be more. Quite REVERSE happens in a cold SUBSTANCE. As the particles vibrate very less, there will be less diffusion.I hope it helps U.....(. ❛ ᴗ ❛.)

For p-p OVERLAP both atoms MUST have unpaired electrons in p-orbitals.H- 1s 1 Be- 1s 2 2S 2 Cl- 1s 2 2s 2 2p 6 3s 2 3p 5 F- 1s 2 2s 2 2p 5 Here, only 'F' and 'Cl' have unpaired electron in vacant shell. But Cl is forming BOND with Be which has s-orbital. while 'F' has 'p' orbital and it is shairing electron with other p-orbital of 'F'.

n chloride is formed by the UNION of hydrogen ION and the chloride ion.Explanation:the valency of hydrogen is EQUAL to 1 where is the valency of chloride is equal to -1. As a result of this they form a bond with each other resulting in the formation of hydrochloric ACID. Calcium chloride is formed by the union of two chloride ion and one calcium ion. This is because calcium has a valency of plus two and chloride has a valency of -1. It is a type of electrovalent Bond.
