Analysis
The following equations represent each actual reaction that occurred for the reactions studied. First PREDICT the products and BALANCE each equation. Then CLASSIFY the reaction as one (or more) of the five general types of reactions – synthesis, decomposition, single displacement, double displacement, or combustion.

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.
