<span>How many atoms are present per cubic centimeter of W?

</span><span>Since it is a BCC cell, then it will have 4 atoms per unit cell.


As a solid, W adopts a body-centered cubic unit cell. How many unit cells are present per cubic centimeter of W?
</span>(19.3 g/cm^3)( 1 mol / <span>183.84 g) ( 6.022x10^23 atoms / 1 mol ) ( 1 cell / 4 atoms) = 1.58x10^22 cells / cm^3</span><span>

Hope this helps.</span>

The pOH of a solution is 10.75. What is the concentration of OH– ions in the solution?. A. –1.031 M. B. 1.778 x 10–11 M. C. 5.62
zloy xaker [14]
We are given the pOH of the solution of 10.75. pOH is the property of the solution that is related to the OH ion concentration of the solution. THe formula to be followed is pOH = -log (OH); OH- = 10^-pOH. In this case, OH-  = 10^-10.75 equal to B. 1.778 x 10^-11 M

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.

Which electron configuration represents the electrons of an atom in an excited state? * 2-3 2-7-1 2-8 2-8-1​
Lemur [1.5K]

2-7-1

<h3>Further explanation </h3>

Electrons can move the shell up or down by releasing energy or absorbing energy  

Excited electrons show higher electron transfer to the shell by absorbing energy  

So it can be concluded that there are 2 conditions:  

Ground state is the state of electrons filling shell with the lowest energy levels.  

Excited state is the state of electrons which occupies a higher energy level  

The state of excited electrons can be seen from the presence of electrons which do not fill the skin completely but fill the skin afterward  

2-7-1

From its 8 electron configuration, filling 3 shells, 2 electrons in the firs shell, 7 electrons in the second shell and 1 electron in the third shell

the electrons in the third shell should fill the electrons in the second shell first according to Aufbau rule (lower energy shells)

\tt  1s^22s^22p^4\rightarrow ground~state\\\\1s^22s^22p^33s^1\rightarrow excited~state
