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.
Answer:
Three main processes control mountain height: lateral support of mountains from tectonic forces, which stops mountains from collapsing under their own weight or pushes them up against gravity; climate-controlled erosion; and isostasy, which keeps mountains afloat on the hot and soft mantle material.

Answer:
4.77 is the pH of the given buffer .
Explanation:
To calculate the pH of acidic buffer, we use the equation given by Henderson Hasselbalch:
We are given:
= Dissociation constant of propanoic acid =
pH = ?
Putting values in above equation, we get:
pH = 4.77
4.77 is the pH of the given buffer .
