The atomic orbitals of the central atom mix to form hybrid orbitals are one s and three p.
<h3>Which atomic orbitals are used to form hybrid orbitals?</h3>
Pauling supposed that in the presence of four hydrogen atoms, the s and p orbitals form four equivalent combinations which he called hybrid orbitals.
<h3>How many bonds does PF5?</h3>
Phosphorus pentafluoride has 5 regions of electron density around the central phosphorus atom (5 bonds, no lone pairs).
The resulting shape is a trigonal bipyramidal in which three fluorine atoms occupy equatorial and two occupy axial positions.

THAT IS TOUGH GIRL HOPE YOU FIND THE ANSWER
<span>Petrolyn motor oil is a combination of natural oil and synthetic oil.
</span><span>it contains 8 liters of natural oil for every 5 liters of synthetic oil.
</span>natural oil / synthetic oil
8 / 5
let x= liters of synthetic oil and
728-x = liters of natural oil
8/5 = 728-x/x , 8x = 5 (728-x)
8x = 3640-5x
8x+5x = 3640
13x = 3640
x = 280 litres
280 liters of synthetic oil is needed to make 728 liters of petrolyn oil.
n = m/M = 15/102.894 = 0.1457811 moles
c = n/V = n / 0.25 = 0.58312438 moles/dm3
