Option D. maintain their positions.

Pressure does not modify the relative position of the atoms in solid matter. The atoms are kept in position by the atomic and molecular bonds  whose length is a feature of every pair of atoms.

For example, all the bonds of C-C and C-H in the wood will have the same bond length

Pretend that you are the size of an atom, observing a reaction between a potassium atom and a fluorine atom. Write an account of
Crazy boy [7]
 <span>Each atom in an ionic compound tends either to empty or complete the shell to 8 electrons. So when the number of electrons on the external shell is near 8 , the atom tends to attract electrons to complete the shell giving a positive ion called anion 
Conversely when the number of electrons is small the atom gives these electrons to form a positive ion called a cation</span>

Calculate the molar solubility of CaF2 at 25°C in a solution that is 0.010 M in Ca(NO3)2. The Ksp for CaF2 is 3.9 x 10-11.
madreJ [45]

Answer:

Molar \ solubility=3.12x10^{-5}M

Explanation:

Hello,

In this case, for the dissociation of calcium fluoride:

CaF_2(s)\rightleftharpoons Ca^{2+}+2F^-

The equilibrium expression is:

Ksp=[Ca^{2+}][F^-]^2

In such a way, via the ICE procedure, including an initial concentration of calcium of 0.01 M (due to the calcium nitrate solution), the reaction extent x is computed as follows:

3.9x10^{-11}=(0.01+x)(2*x)^2\\\\x=0.0000312M

Thus, the molar solubility equals the reaction extent x, therefore:

Molar \ solubility=3.12x10^{-5}M

Regards.
