In geology and mineralogy, a mineral or mineral species is, broadly speaking, a solid chemical compound with a fairly well-defined chemical composition and a specific crystal structure, that occurs naturally in pure form.

Answer:
<em>The pKa is 13.0.</em>
Explanation:
pKa + pKb = 14
Given, Kb of trimethylamine = 6.3 × 
pKb = - log (6.3 × )
= 1.0
⇒ pKa = 14 - pKb = 14 - 1.0
<u>pKa = 13.0</u>
<em><u></u></em>
<em>Check: For most weak acids, pKa ranges from 2 to 13.</em>
Answer: I believe it’s the second one
(F)
Explanation:
Answer: option B) proton-electron.
The particles inside a salt crystal are ions. The electrostatic attraction between the positive ions are the negative ions is responsible for the crystal structure. In last stay, the protons are responsible for the positive charge and the electrons for the negative charge. Then you can say that the interaction proton-electron is responsible for the force of attraction between the particles in a salt crystal.
