Which of the following best describes a bronsted-lowry acid-base reaction?
o
a acid + conjugate acid = base + conjugate base
o
b
acid + conjugate base = base + conjugate acid
o
c acid + base = conjugate base + conjugate acid
o
acid + base = metal + nonmetal

c Acid + base = conjugate base + conjugate acid

Explanation:

In a Bronsted-Lowry acid-base reaction, the original acid gives up its proton and becomes a conjugate base. In like manner, the original base accepts a proton and becomes a conjugate acid. For every acid, there is a conjugate base and for every base, there is a conjugate acid:

                           HA    ⇄     H⁺     +      A⁻

                          acid                         conjugate base

                         B         +     H⁺         ⇄        HB⁺

                      base                            conjugate acid

a polar bond is formed when electrons are shared unevenly between atoms
