To illustrate the Lewis structure,
P has 5 valence electrons
O has 6 valence electrons (each for 4 oxygen)
And finally, for every negative charge, there is an additional valence electron
We should add these all up = 5 + 24 + 3 = 32 valence electrons
With this, we can be guided to illustrate the lewis structure as P as central atom and the 3 oxygen each with a single bond with P and 1 oxygen with a double bond with P. We place the valence electrons until octet rule is satisfied,
we will be left with 12 lone pairs for phosphate ion.
A) energy

Answer:
C) polar covalent bonds
Explanation:
Polar covalent bonding can be regarded as a chemical bond that involves a pair of electrons which is
unequally shared between two atoms.
The electron are not shared equally as a result of one of the atom spending more time with the electron compare with the other atom. It is one whereby atoms having different electronegativities involves themselves in sharing electrons in a covalent bond
The answer is correct orientation and sufficient energy. Answer choice D
Answer:
P = 746.2 mmHg or 0.9818 atm
Explanation:
First, we have a sample gas (This can be hydrogen, argon, nitrogen or any other gas) that was collected with a pressure of 778 mmHg. We also know the vapor pressure which is 31.8 mmHg. To get the pressure that the gas is exerting, we can assume that the atmospherical pressure is the total pressure of the whole system. Therefore we can use the following expression:
Pt = Pw + Pg (1)
Where:
Pt: total pressure
Pw: water pressure
Pg: gas pressure
From (1) we can solve for the gas pressure and have:
Pg = Pt - Pw
Replacing the data we have:
Pg = 778 - 31.8
<h2>
Pg = 746.2 mmHg</h2><h2>
This would be the pressure of the gas</h2>
If you want this value in atm, you should divide it by 760 mmHg (Conversion from mmHg to atm):
Pg = 746.2 / 760
<h2>
Pg = 0.9818 atm</h2>
