Question

the p-p bond energy is 'x' KJ/mole. then the energy needed for the dissociation of 124g of white phosphorus is??

Answer 1

 'x' KJ/mole means we need 'x' kJ of energy to dissocate a mole of P-P bond


White phosphorus or yellow phosphorus exists as molecules made up of 4 atoms in a tetrahedral structure. It can simply be referred to as tetraphosphorus (P4).


Each mole of P4 has 6 P-P bonds (See the attached image).


To dissociate 1 mole of P4 we need 6x kJ of energy.



P = 31

P4 = 31x4 = 124g/mol


To dissociate 124g (1 mole) of P4 we need 6x kJ of energy

 

Answer 2

Answer:

Explanation:

'x' KJ/mole means we need 'x' kJ of energy to dissocate a mole of P-P bond

White phosphorus or yellow phosphorus exists as molecules made up of 4 atoms in a tetrahedral structure. It can simply be referred to as tetraphosphorus (P4).

Each mole of P4 has 6 P-P bonds (See the attached image).

To dissociate 1 mole of P4 we need 6x kJ of energy.

P = 31

P4 = 31x4 = 124g/mol

To dissociate 124g (1 mole) of P4 we need 6x kJ of energy
