Answer=3
The compound has an ionic bond.
Answer:
of are found in 39.5 grams of .
Explanation:
Atomic weights : P= 31, F= 19,
molar mass of = 1 atomic weight of P+ 5 atomic weight of
F= 31+5 19
= 31+95
=126 g/mole
moles in 39.5 gm of
=
=
=0.3134 moles
1 mole of any substance contains
0.3131 moles contains 0.3134
Therefore, of are found in 39.5 grams of .
This type interaction is called the London dispersion force. These are temporary forces that happens when electrons of two adjacent atoms occupy positions that will result to temporary dipoles. The constant motion of the electrons will cause to form an instantaneous dipole when the electrons are unsymmetrically distributed. These forces are present in nonpolar substances.
