Please say which is the anode (oxidation) and which is the cathode (reduction) 2H+ + 2e- ➖> H2 (g)

2I- ➖> I2 + 2e-

Explanation:

1st one will be cathodic reaction and reduction will occur since electrons are being gained and hydrogen goes from +1 to zero oxidation state.

2nd one will be anodix reaction and oxidation will take place because Iodide ion's oxidation number increases from -1 to 0

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.
