Geologists have a rule of thumb: when molten rock cools and solidifies, crystals of compounds with the smallest lattice energies
lutik1710 [3]

Geologists have a rule of thumb: when molten rock cools and solidifies, crystals of compounds with the smallest lattice energies appear at the bottom of the mass because of high power of solubility.

<h3>What is lattice energy? </h3>

The lattice energy is defined as the energy change upon the formation of one mole of crystalline ionic compound from its same constituent ions, that are assumed to be initially in the state of gases. It is also defined as measure of the cohesive forces which bind ionic solids together.

As the lattice energy of the ionic compound increase the solubility of that particular compound decrease. Hence compound which have low lattice energy are more soluble than compound having high lattice energy. When molten rocks cools and solidified, the compound having smallest lattice energy become more soluble than crystals of compound which have large lattice energy. Therefore, crystal of compound with the smallest lattice energy start appearing at the bottom of the mass.

Thus, we concluded that due to high solubility power of compound with low lattice energy appear at the bottom of the mass.

What is the percent composition of phosphoric acid H3PO4
Agata [3.3K]
Hey there!:

Molar mass H3PO4 = <span>97.9952 g/mol

Atomic Masses :

H = </span><span>1.00794 a.m.u

</span>P = <span>30.973762 a.m.u

</span>O =  15.9994 a.m.u<span>

H % =  [ ( 1.00794 * 3 ) / </span> 97.9952  ]  * 100

H% = <span>3.0857 %

P % = [ ( </span>30.973762 * 1 ) / 97.9952 ] * 100

P% = <span>31.6074 %

O % = [ ( </span>15.9994 * 4 ) / 97.9952 ] * 100

O% = <span>65.3069 %


Hope this helps!</span>
