Answer:
It is the energy the ions absorb when they form a crystalline compound.
Explanation:
Lattice energy is the energy released upon the formation of a crystal lattice structure.
Krafla Volcano in Iceland,
Answer:
Two, KCl and PbCl₂.
Explanation:
Hello!
In this case, since the addition of chloride ions promote the following three ionic reactions:
![Ag^+(aq)+Cl^-(aq)\rightleftharpoons AgCl(s)\\\\K^+(aq)+Cl^-(aq)\rightleftharpoons KCl(aq)\\\\Pb^{2+}(aq)+Cl^-(aq)\rightleftharpoons PbCl_2(s)](https://tex.z-dn.net/?f=Ag%5E%2B%28aq%29%2BCl%5E-%28aq%29%5Crightleftharpoons%20AgCl%28s%29%5C%5C%5C%5CK%5E%2B%28aq%29%2BCl%5E-%28aq%29%5Crightleftharpoons%20KCl%28aq%29%5C%5C%5C%5CPb%5E%7B2%2B%7D%28aq%29%2BCl%5E-%28aq%29%5Crightleftharpoons%20PbCl_2%28s%29)
We can infer that both silver chloride and lead (II) chloride are precipitated products as their Ksp are 6.56x10⁻⁴ and 1.59x10⁻⁵ respectively, which means they are merely soluble in water.

Explanation:
Not much of one
Global wind patterns are mainly determined by unequal heating of the earth's surface, changes in air pressure, and earth's rotation. Change in air pressure: Air mainly circulates due to change in air pressure. It moves from a region of high air pressure to the region of lower air pressure.
