How does the brønsted-lowry theory define acids and bases?

A  Brønsted-Lowry acid is a proton donor.

A Brønsted-Lowry base is a proton acceptor.

Explanation:

The NH₃ is a Brønsted-Lowry base because it accepts a proton to become NH₄⁺.

The HCl is a Brønsted-Lowry acid because it donates a proton to NH₃ and becomes Cl⁻ .

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
