Hydrophobic compounds dissolve in select one: a. ionic solvents o b. low dielectric constant solvents c. high dielectric constant solvents d. polar solvents such as water o if formulating an aqueous solution for parenteral administration, filtered and sterile pyrogen free water must be used. select one: o true o false

Explanation:

(1.)   A hydrophobic compound is defined as the compound that does not dissolve in water and they contain no charge. Hydrophobic compounds are generally organic in nature.

Hence, there occurs no interaction between the two.

(2.)   Pyrogen is defined as any substance that is able to cause fever. Bacterial pyrogens are endotoxins and exotoxins.

And, if both of these toxins are not removed from the body then they tend to interact with the mechanism of drug interaction and hence, these lead to unexpected side effects.

Therefore, the statement if formulating an aqueous solution for parenteral administration, filtered and sterile pyrogen free water must be used, is true.

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!
