Explanation:

Ba: Calcium atoms in bones absorb x-rays, allowing doctors to clearly see the body's skeleton. X-rays can also be used to see blood vessels and internal organs. Special liquids, such as compounds made with the element barium (Ba), are swallowed by the patient, or injected into the bloodstream. The liquids help absorb x-rays, making certain tissues show up more clearly.

N20: Certain chemicals can be used as an anesthetic. Nitrous oxide (N2O) is commonly used in surgery and dentist offices.

C 14H 10O 4: Many acne medications contain benzoyl peroxide (C14H10O4), a compound that releases oxygen during a chemical reaction with skin. The oxygen kills anaerobic bacteria, which cannot live in the presence of oxygen.

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.
