According to solubility rules, which of the following compounds is insoluble in water? A. Cal
2

B. NA SO
2 4

C. AgF

D. AI(OH)
3

The correct answer is - Al(OH)3

Explanation:

At the point when a substance is blended in with a soluble, there are a few potential outcomes. The deciding variable for the outcome is the solubility of the substance, which is characterized as the maximum concentration of the solute. These rules help figure out which substances are solvent, and how much.

According to the 11 rules of solubility rules, the insoluble compound in water is - Al(OH)3

iron and sleel

make siroeel

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
