Which of the following does ((not)) describe a single-displacement reaction?

a. occurs when one element replaces another element in a compound.

b. ab+c > ac+b

c. occurs when a substance is broken down into two or more simpler substances.

d. also called a redox reaction

The correct answer is option C.

Explanation:

Single replacement reaction : It is a type of chemical reaction in which element exchange their position with the position of another element in its compound molecule.

It is also called redox reaction because one element getting oxidized and another one getting reduced.

Hence, the correct answer is option C.

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.

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
