For no2−, write an equation that shows how the anion acts as a base. express your answer as a chemical equation. identify all of the phases i

The chemical reaction in which NO2^- acts as a base is;  H3O^+(l) + NO2^- (aq) > HNO2(aq) + H2O(l)

According to the Brownstead - Lowry definition of acids and bases, an acid is any substance that donates a proton while a base is any substance that accepts a proton. Hence, the NO2^- ion acts as a base in reactions where it accepts a proton to yield its conjugate acid.

In the reaction; H3O^+(l) + NO2^- (aq) > HNO2(aq) + H2O(l), we can see that the NO2^- accepted a proton from H3O^+ to yield its conjugate acid  HNO2.

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.
