Answer:
Barium nitrate or silver nitrate based on the anion our solute contains
Explanation:
I assume the situation is that currently the solute is soluble in water and you wish to make it insoluble.
It really depends on the soluble material you have, however, let's look at some specific cases.
- We have a salt in our solution. Addition of any of the three reagents will produce a double displacement reaction, that is, our cation will be replaced by another cation, either sodium, barium or silver cation.
- According to the solubility rules, all sodium salts are soluble, so sodium nitrate won't precipitate our anion.
- In case our solute contains sulfate, carbonate or phosphate, we may use barium nitrate to precipitate it, as barium sulfate, barium carbonate and barium phosphate are insoluble.
- In case our solute contains chloride, then silver nitrate is the way to go to precipitate it in an insoluble form of AgCl. Similarly, silver would form precipitates with carbonate, phosphate, iodide, bromide and slightly soluble silver sulfate (barium is the choice for sulfate, however).

Explanation:
Answer:
elecreonegativity is the attraction of a bonded atom for the pair of electrons in a covalent bond. this can occur if:
- the nuclear charges are different
- the atoms are different sizes
- the shared pair of electrons are closer to one nucleus than the other
Covalent bond is the term that is being used to describe the bonds in the compounds that are created due to the sharing of one or more electrons. One of the best example of the simplest covalent bond is the bond that is being created when two isolated hydrogen atoms come together to form an H2 molecule. An isolated hydrogen atom has one proton and electron being combined by the force of attraction from the opposite-charged articles. When a pair of isolated hydrogen atom combines, two forces of attraction are created coming from each of the isolated hydrogen atom.
Answer:
The study of the human body as a machine for the performance of work has its foundations in three major areas of study—namely, mechanics, anatomy, and physiology; more specifically, biomechanics, musculoskeletal anatomy, and neuromuscular physiology. Explanation:
