Which of these refers to the strength of an acid? a measure of the quantity of acid dissolved in water designated by molarity an intrinsic characteristic of a particular acid, not related to concentration the amount of hydrogen ions present in the acid the amount of hydroxide ions present in a solution

Option (C) is the correct answer.

Explanation:

The strength of an acid depends on the number of hydrogen atoms attached to it. The more strong and acid, the more easily it will dissociate into ions.

For example,

Thus, we can conclude that the amount of hydrogen ions present in the acid refers to the strength of an acid.

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.
