Amines are derivatives of
Ammonia (NH₃) in which atleast one hydrogen atom is replaced by an alkyl group. Amines are further classifies as;
Primary Amines: In primary amines the nitrogen atom is attached to two hydrogen atoms and one alkyl group.
Secondary Amines: In secondary amines the nitrogen atom is attached to two alkyl groups and one hydrogen atom.
Tertiary Amines: In tertiary amines the nitrogen atom is attached to three alkyl groups, hence it has no hydrogen atom.
Below are three isomers of tertiary amines with molecular formula
C₅H₁₃N.
The given question is incomplete. The complete question is as follows.
The solubility product of calcium fluoride () is at 25 degrees C. Will a fluoride concentration of 1.0 mg/L be soluble in a water containing 200 mg/L of calcium?
Explanation:
Reaction equation for the given chemical reaction is as follows.

Therefore, expression for
will be as follows.
=
Also, moles of per liter = \frac{\text{mass of F^{-} per L}}{\text{molar mass of F}}[/tex]
=
= 
Hence, ![[F^{-}] = \frac{\text{moles of F^{-}}{volume}](https://tex.z-dn.net/?f=%5BF%5E%7B-%7D%5D%20%3D%20%5Cfrac%7B%5Ctext%7Bmoles%20of%20F%5E%7B-%7D%7D%7Bvolume%7D)
=
= M
Now, moles of per L = \frac{\text{mass of Ca^{2+} per L}}{\text{molar mass of Ca}}[/tex]
=
= M
Also, ![[Ca^{2+}] = \frac{moles of Ca^{2+}}{volume}](https://tex.z-dn.net/?f=%5BCa%5E%7B2%2B%7D%5D%20%3D%20%5Cfrac%7Bmoles%20of%20Ca%5E%7B2%2B%7D%7D%7Bvolume%7D)
=
= M
Hence, ionic product =
=
= 
As, the ionic product is less than the
, this means that the fluoride will be soluble in water containing the calcium.
Ruining her land. Fracking can interrupt farming and can kill crops.
The kinetic energy of particles depends on temperature. As temperature increases, the kinetic energy of particles increases.
Temperature is defined as a measure of the average kinetic energy of the molecules of a substance. The higher the temperature of a substance the greater its kinetic energy.
From the foregoing, when the temperature is increased from 400K to 500K, greater kinetic energy is imparted to the molecules of the substance hence they move faster according to the kinetic theory of matter.
