Which reaction is a decomposition reaction? a. 2kclo3 → 2kcl + 3o2 b. 4na + o2 → 2na2o c. zns + 3o2 → 2zno + 2so2 d. 2nabr + caf2 → 2naf + cabr2

Explanation:

There are five basic general types of chemical reactions:

The given reactions are:

Which is, indeed, a decomposition reaction because the reactant, KClO₃, is a single substance that undergoes a reaction in which it yields two new substances, known as products: KCl and O₂.

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.
