G Which three statements accurately describe the blood buffering system in humans? The blood buffering system maintains the pH of blood near 7.4. The blood buffering system utilizes the H 2 CO 3 / HCO – 3 conjugate acid/base pair. The blood buffering system depends on the ionization of H 2 PO – 4 . The blood buffering system utilizes the acetic acid/acetate conjugate acid/base pair. The blood buffering system is facilitated by the enzyme carbonic anhydrase, which interconverts carbon dioxide and water to carbonic acid, ionizing into bicarbonate and H + .

Which is a difference between molecular compounds and ionic compounds? select the correct answer below: question 5 options: molecular compounds typically form between a metal and a nonmetal, while ionic compounds typically form between nonmetals. molecular compounds result from the transfer of electrons between atoms to form ions, while ionic compounds result from the sharing of electrons between neutral atoms. molecular compounds are formed of discrete, neutral molecules, while ionic compounds are formed of large repeating arrays of opposite charges. molecular compounds have high melting points and high boiling points, while ionic
