3 0

B:Oxygen and silicon

Explanation:

Most minerals on the earth's surface contains oxygen and silicon. Silicon and oxygen are the most abundant elements we find in the rock minerals on the earth surface.

  • Silicon and oxygen forms the SiO₄⁻ tetrahedron through which several minerals are formed.
  • These minerals built on the network of the tetrahedron are referred to as silicates.
  • Several silicate minerals are known:
  1. Quartz
  2. Feldspars
  3. Olivine
  4. Biotite
  5. Pyroxene

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.

1. What amount of ammonia (in moles) is produced by the reaction of 4.00 mol H2 with 3.00 mol Nz?
ArbitrLikvidat [17]
<h2>Answer:  6 moles</h2>

<h3>Explanation:</h3>

3 H₂    +    N₂   →   2 NH₃

   ↓            ↓

4 mol       3 mol

Since the moles of N₂ is the smaller of the two reactants, then N₂ is the limiting factor (the reactant that will decide how much ammonia is produced since it has the smaller amount of moles). ∴ we have to use it in calculating the number of moles of ammonia

The mole ratio of N₂ to NH₃ based on the balanced equation is 1 to 2.

∴ the moles of NH₃ = moles of N₂ × 2

                                =  3 moles × 2

                                = 6 moles
