When a solid compound is formed from chemicals which are in solution, it is called a?
SVETLANKA909090 [29]

Answer: precipitate.


Explanation:


1) When the product of the reaction between the chemicals in the solution is insoluble, then it cannot remain in the solution and it will precipiate, forming a solid substance.


2) That happens, for example, when you have two solutions with different solutes, mix them together, the solutes can react chemically with each other, yielding a product that is insoluble.


3) A typical example of such kind of precipitation reactions is athe neutralization of an acid and a base.


Acid + Base = salt + water


If the salt is insoluble in water then it will form a a precipitate (solid), if the product is soluble in water then it remains as an aqueos ions in the solution.

Why might a geologist ask an analytical chemist to help identify the minerals in a rock.
Galina-37 [17]

 A geologist will ask an analytical chemist to help identify the minerals in a rock because an analytical chemist studies the composition of matter and, therefore, can identify the minerals.

The analytical chemist does this by determining the crystal structure as a matter of routine using X-ray and electron diffraction techniques.
