Provide the bronstead-lowry de finition for an "acid" and a "base"

According to the Bronsted-Lowry conjugate acid-base theory, an acid is defined as a substance which looses donates protons and thus forming conjugate base and a base is defined as a substance which accepts protons and thus forming conjugate acid.

For example:

Here, is loosing a proton, thus it is considered as a bronsted acid and after losing a proton, it forms which is a conjugate base.

And, is gaining a proton, thus it is considered as a bronsted base and after gaining a proton, it forms which is a conjugate acid.

The sequence of the acids and bases in the above equation are:

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
