NH3–NH4Cl is a/an _______ that helps regulate the pH of a system.
1 answer:
NH3–NH4Cl is a/an <u>Buffer</u> that helps regulate the pH of a system.
A buffer solution ( pH buffer or hydrogen ion buffer) is an aqueous solution consisting of a mixture of a weak acid and its salt formed from conjugate base, or weak base and its salt formed from conjugate acid.
Acidic Buffer : Consisting of a mixture of a weak acid and its salt formed from conjugate base.
Basic Buffer : Consisting of a mixture of a weak base and its salt formed from conjugate acid.
The given solution is NH3-NH4Cl is Basic buffer which is composed of weak base(NH3 ammonia) and a salt(NH4Cl ammonium chloride) formed from its conjugate acid(HCl hydrochloric acid).
composed of weak base and its salt and is considered as Basic Buffer.

Answer:
The structures are attached in file.
Hydrogen bonding and intermolecular forces is the reason for ranks allotted.
Explanation:
In determining Lewis structure, we calculate the overall number of valence electrons available for bonding. Making carbon (the least electronegative atom) the central atom in the structure, we allocate valence electrons until each atom has achieved stability.
In order of decreasing affinity to water molecules:
This is due to the fact that the will accept protons more readily than the bicarbonate ion,
. Carbonic acid,
will not accept any more protons, hence it is the least attractive to water molecule, even though soluble.
